The Manual - G.A. Pettigiani - 2010

[Rein]

Pettigiani tries to define the notion "grené"

"decimos que la trama es grené cuando el granulado es sumamente proljo, los poros de una fila no estan alineados verticalmente con la siguiente sino que esta exactamente en el medio de los dos superios o inferios. Esto forma en la tramaunas diagonales de distinta inclinacion, como lo han analizado algunos estudiosos de esta serie"

It winds up to saying that the rhombos should be very cloear and prolonged, the hole in between the threads do not lie right on top of each other but shift aside half length. Thus, a sort of diagonals gets shaped that some students of this series have analyzed.

I can not agree more with him as he suggests here having come to know about the strange blue diagonal lines I have displayed here several times!

We have TWO parallel watermarks with a symmetrical paper mesh in the PyR I period, the first with a 30/20 density:






- the black line indicating the direction of paper
- the blue lines the virtual diagonals of the mesh
- the yellow triangle formed by the hearts of 3 suns
- the red line the distance from the heart of the suns within the line of AЯ
- the green line the distance between 2 identical lines of AЯ
- the violet lines the diameters of the Sun

Paper: parallel to the line of RA
Symmetrical mesh
Mesh - virtual shape: lozenges with the longer diagonal parallel to the direction of paper
Sun: round
Diameter: 9.5 mm
Horizontal distance between the hearts of the sun: 18 mm
Vertical distance between 2 identical lines of RA: 30 mm
Letters of RA: meet at the base (height 4.5 mm width 8 mm)
Color: white
Thickness: medium
Surface: without coating - matt
Manufacturer: English.
Used for the first time in 1939

What seems to be not so accurate is the diameter of the Sun! How to measure it exactly???

There can be made some minor distinctions as to the way the "trama" is clear or not so clear and hence rather "closed" [cerrada]. Pettigiani denotes this by using " A' " and Tony Rubiera has his 1E3a which according to him only got used since 1939 ....

No doubt, this will keep the students busy for some time

Type B of Pettigiani is a well-known one rather referred to as Austrian (Austriaco).

This paper was manufactured by the Austrian paper mill of Curt Berger. No trace of him in the WWW

As trama it is referred to as "granulado" as it still has a symmetrical paper mesh but the rhombos are not so clear as with its predecessor!

This type of paper had been used around 1928 for the Airmail stamps and the 1 peso of the José de San Martin issue of 1923! The main difference with the use of this paper in the P&R I period is the fact that the felt side had always been gummed resulting in a "RA" reading from the back of stamp. Pettigiani does not seem to have noticed that apart from the smaller suns the horizontal distance between 2 alternate suns - i.e. along the line of AЯ - is 32mm instead of 35mm for most other wavy rays and straight rays watermarks!

Type "C" of Pettigiani is upposed to come from England in 1938.

Called often "Mate Lustroso". In the typology of the watermarks it is of type II that we will also in the so-called Dutch paper..... What makes us wonder whether this paper is different!



Leopoldo Tenorio Casal gave some very accurately looking details about the typographed stamps of P&R I - the 1c Sarmiento, 5c Moreno and 10c Rivadavia. They are so detailed and measured in a completely different [from Merlo a.o.] that I tend to confide a lot in this!

The 5c of 24.03.1940 has a diameter of 10mm, the vertical distance between 2 alternate rows of suns is 30mm and the horizontal distance between 2 suns is 17.2mm! This is in line with my earlier remarks about the horizontal heart-to-heart distance between 2 alternate suns is 35mm and the vertical heart-to-heart distance between 2 alternate suns is 30mm!

Casal also refers to several other face values having been printed on the same type of paper and here we get confronted with the possiblilty of him referring to what we call the Dutch paper!

I am still not sure whether we have just ONE Dutch paper in that period!

The 1938 Pettigiani refers to is not clear to me! It refers to which stamp in particular????

MT 412 = 14.04.1940 Union Panamericana
MT 417 = 05.12.1941 General Lavalle

both printed in photogravure!

[Rein]

Pettigiani says there are no references outside P&R I for the Austrian paper, the only stamps coming close are the Airmail stamps of 1928!

I do not agree as I have said here above, but we also have the Housing Congress of 1939 October 2nd!


The orthogonal watermark with symmetrical paper wire - direction of paper parallel to the short side of the stamp "m":






Measuring the horizontal distances between the 1st and the 3rd sun of this last version: 32mm, we may be quite sure that this type of paper belongs to the so-called: Austriaco or 1E2 !!!

Rein,

Undoubtedly it is papel austríaco! A few weeks ago a member of my club told me a stamp unknown to be printed on such paper appeared. Upon your mail I called him to confirm what stamp it was and he confirmed it was the Housing stamp.
This is a fascinating aspect of philately: it always surprises you with a new challenge. But what is strange for me is the contemporarity of this discovery, unless you knew of it existence from long ago.

Do not be surprised if Kneitschel or Klass didn't mention these papers. It happens that JG finally accepted our 'preaching'
of the importance of classifying different papers. I wrote my PyR I monography because I was tired of seeing collectors being
cheated by dealers that sold them the common papers by the good ones, and to point out the existence of real rarities concerning papers.

Type "D" of Pettigiani is better known as "Holandés"

Also the first occurance here is the 02.10.1939 Housing Congress stamp!

The parallel watermark with symmetrical paper wire - English paper papel inglés - direction of paper parallel to the long side of the stamp "M":





The orthogonal watermark with symmetrical paper wire - Dutch paper papel holandés - direction of paper parallel to the long side of the stamp "M":





But is this the typical Holandés we know of the 1940 P&R I stamps????

[Rein]

Reference stamps given by Pettigiani are:

MT 413 = 03.10.1941 Avellaneda in offset-litho
MT 414 = 26.10.1941 Banco de la Nacion in photogravure
MT aero 20-24 = 23.10.24 Airmails in photogravure

are they really different from the before mentioned on "mate lustroso"????

Not surprisingly Tony Rubiera hadn't differentiated them and classified them all under 1E4!

[Rein]

Type "E" by Pettigiani is often referred to by "Tela"!

Other than the 1E1 and 1E3a that hasve a 30/20 density we have a paper with a 24/20 density = 1E3c = Tela!




Direction of paper: parallel to the line of RA
Symmetrical mesh
Mesh - virtual shape: little squares
Sun: round
Diameter: 10 mm
Horizontal distance between the hearts of the sun: 17.5 mm
Vertical distance between 2 identical lines of RA: 30 mm
Letters of RA: see picture above!
Used for the first time in 1941.

This paper is named by various authors as follows:
Rubiera 1E3c; Bardi MI 4, Moscatelli, Merlo Tela

[Rein]

Its origin is England - the same manufacturer as that of A???? The type of watermark is according to Pettigiani type I so that is OK! It is considered by him to be of another type of Trama but as I have said before it is only a matter of density!

The references in the commemarives start with the French and Beutti stamp of February 1941. So why 1940 as a start???

In 1941 an English type of paper got introduced for Argentinean stamps - not only the definitives but also most of the Commemoratives of that period.

The paper mesh we see comes from a weave that has vertical lines/threads and horizontal threads of various densities; the usual density is 28-30 vertical threads(warp) per horizontal centimeter AND some 20 horizontal threads (weft) per vertical centimeter! The gauges noted as follows - 28/20, 30/20, 24/20, etc...

The so-called Tela paper has a grid/wire gauge of 24/20; I will show you the original English stamps as well for comparison.

24/20 diagonal lines at 50 and -50 degrees





28/20, diagonal lines at 58 and -58 degrees

As this type of paper had been used for quite a long period: 1941-1945 it is not strange that we can distinguish subtypes!

Pettigiani refers to three of them:

a. tela marcado
b. tela algodonoso
c. tela traslucido

It will be good to have clear scans of all 3 subtypes someday

Type "F" is the so-called "rayado vertical" or simply a parallel watermark like "A" which had a symmetrical paper mesh. This onje has an asymmetrical paper mesh. As it comes from the same manufacturer - Wiggins, Teape and Alex Pirie [Portals in the mean time?] it probably had the same dandy-roll used but with a different wire! Or maybe just on a different paper machine?

Pettigiani claims it is a "papel mas complicado"! Why???

One reason is the chronological spread: 1944 - 1950/1951 -1956.... That is a bit cryptical!

The 1944 part is relatively easy as several face values have been found with early dates [1944/1945] and the asymmetrical paper mesh - the 25c Labrador and the 50c Petroleo for instance. Apart from that the 17.02.1944 Earthquake stamps - the only "commemorative" in a period where most had "Tela"!!!!

1950/1951 is probably the period where we more generally found this type of paper!

But 1956???

The 1947 20c Antartida stamp is referred to [MT 486I] as the earliest one, bu bear in mind that also Rayos Rectos occurs for this stamp so we need to know precise dates of use!

With MT 505 were are amidst the 1950 San Martin commemoratives of 1950!

MT 564-566 the 01.09.1956 Provincialisacion stamps are certainly not the Last of the Rayado Vertical

The various subtypes of the rayado vertical certainly deserve a more detailed study which should include good scans to everybody will know what to look for!

Just separating the "trama difuso" or "trama cerrada' as paper F" is maybe a but simplistic....
