For some strange reasons NO Polish catalogue has ever mentioned the offset-litho printed stamps!

The one in the middle had been printed in Kraków in photogravure with an imprint at the bottom!

That is the problem NO experts catalogues or handbooks since the 1960-ies do mention anything about offset-litho being used! Including the ones that have transcribed the information straight from the Archives [then still communist's!]daa1406 escribió:Hi Mr. Rein, welcome to back.
Regarding the stamps you speak only of the Michelcatalog?
Fischer and expertise catalogs include that information.
