10c Rivadavia Red heights compared

I find that the type I stamp is slightly longer than the type II stamp. In these images the type I stamp is the first stamp from left to right.



Here are the three types of selvage:

1. Type I with six horizontal lines.
2. Type II with solid horizontal bar.
3. Type II with field of vertical lines.





I have also checked the 'Servicio Oficial' and found it to be Type II.

10c Rivadavia Red Type II Plate Variety

I find these two specimens, one with lower selvage.

25c1E4 range of use

This stamp saw use during 1940. This first specimen may be a postmark error since all 1E4s I have come across for all denominations date from 1940.

25c1E3a range of use

This stamp saw first use early in 1939. This stamp is identical to the 1E1 except for the color and translucency of the paper. The back of the stamp has a symmetrical rectangular grid.

25c1E1/2 range of use

The 25c1E1 was issued January 1, 1936 and is uncommon.





The 1E2 was in use during 1937. This early use specimen dates from late 1936.

10c Rivadavia Red Type II Inking 'eye' varieties

I do not find any of these curiosities to be repetitive.
