type I cancels

These cancels were used in 1935/36. This format was mostly replaced during 1937, even though a small number of small towns kept the format well into the 1940s.



I have seen these for I-1 to I-5. I wonder if there's a 6, 7,...

question about a postmark

I do not know the meaning of the 3-I-3 format for this postmark.

divide and conquer the 10c Rivadavia Brown

This stamp has to be the most difficult group of printings to type for this series. I have decided that I need to scope these issues in detail before moving forward with the next batch of groups.



The issues as I know them right now are:

1. The very rare 1Ex printing that is NOT typographed, mentioned in one of the reference articles I have posted authored by Tenorio.
2. The typographed issue on the CL1 paper from 1939, the one with a porous look.
3. The typographed issue on the CL1 paper from 1943, for which there is a CL1A and a CL1B?
4. The NGR issue.
5. The NOP issue.
6. The second watermark issues, for which looks like there are two, one reddish and one dark brown.
7. The second batch of clays, the very dark browns from 1950.
8. The 1L issue with normal design size. There may be more than one 1L paper.
9. The small die 1L issue.

two proofs?

Here is how I clasify all errors and stamps that were not regularly issued:

1. Overprinted specimen, "muestra"
2. Printing proofs. I still have doubts in case some proofs may have been printed on regularly issued papers and colors. The following example is printed on unwatermarked india paper, commonly used for US proofs in the 19th century.



3. Not perfed
4. Poorly perfed
5. Printed on the gum side
6. Double impresions
7. "printer's waste" and the example below seems to be, but I am not sure. It is printed on both sides on india unwatermarked paper.

a postal entire overprinted "sin valor postal"

These entires I am told were used officially.

a post office box receipt

Here are several images of this receipt.

The stamp for 12 pesos fee:



The 1 peso stamp seems to have a minor plate variety.





And the same seems to be the case for the 5 pesos stamp.

First typographes issues and the 1E2 issue

I have grouped the 1c/5c typographed and the 5c departmentals in group 6.

The "servicio oficial" for 5c/10c typogaphed and the 15c Small Format Cattle dark blue I place in group 7.



The 1E2 issues are in group 8, and these saw use mostly during 1937. I do not find any overprinted "servicio oficial" and I may be missing a few of the regular issues.



tony

1 peso without boundaries departmentals

I have placed these stamps in group 5, and find some overprints on any or both of 1E1 and 1E2.



Here are all the images

Those overprinted along the top are all 1E1 in my limited sample, and this may be an indication that these were overprinted first.



I also find a specimen with a field of ink dots, similar to one I have shown before.

question about usage to Germany

Does anyone know what this printed tape mean?

postal entire

I would like to know why this postal entire has edge perforations.

a few slogans

Here is a small selection from the 1930s and 1940s.

20c Bull (20cLC) first and second watermark

This stamp is much more complicated than I imagined. Now that I have looked at a reasonable number of these, I find the following printings:

Medium color, first watermark, 1E3, flat paper, from 1942, vertical watermark in both directions





Medium color, second watermark diffuse, 2D, white flat paper, from 1943?, horizontal watermark





Another one on thicker paper, poorly perfed





Vivid colors, second watermark-straigh rays, 2C, white rough paper, 1949, horizontal





Vivid colors, second watermark-straigh rays, 2C, white rough paper, 1949, vertical





Dark colors, first watermark on the first late paper, 1L1, from 1951, vertical in both directions





Dark colors, first watermark on the first late paper, 1L1, from 1951, vertical in both directions, worn printing





Light colors, looks like straight rays, but is first watermark on the first late paper, 1L1, from 1951, vertical in both directions





Here are links to additional specimens-I doubt I got all the varieties.

varieties in the background color for the 20c Bull (20cLC)

I have noticed two interesting varieties in in the background color. In the large block I have previously shown, I find one stamp with the background more displaced than the stamp left of it.



In one of the 1E3 specimens, I find a curious background printing flaw on the outside edge.





Have you seen these varieties or similar ones in your collections?
