In the case of Argentina with e stamps printed on a sheet-fed photogravure press, the gumming of the coated side was certainly a mistake!Rein escribió:The coating at the back is spectaculiar!
The print is normal with a direction of printing [ink flowing] towards the left; the back of the stamp shows the typical pockmarks! It seems that the gum had been applied on the coating side of the paper!
Also clearly visible the RA of the watermark - RA instead of AЯ!!!!
