Which stamps are we talking about???
1c D.F. Sarmiento,
5c M. Moreno,
10c B. Rivadavia
20c Ganaderia
5c José de San Martin
20c and 40c JSM
2p, 4p, 8p, 10p and 20p JSM
so far all in portrait shape.
50c Puma;
1p Caballo
both landscape.
Most of them have been printed on coated paper (papel tizado) but some also exist on uncoated paper (papel "mate"), but the 2p JSM and the last 2 stamps (50c, 1P) are on uncoated paper only.
As stated in the first alinea, the direction of paper has been the same for all! At least that was what I though it to be!
I have seen 1 stamp, just ONE single copy, of the 40c JSM, with the direction of paper horizontal.
If I am right this is the rarest stamp of Argentina
