Below is a cover showing various "cents" values, the more common 5c Moreno and 10c Rivadavia Brown, and the 15c Martin Guemes. Notice the 1c Sarmiento, 5c Moreno, and 10c Rivadavia Brown values are typographed, clay paper types (CLt), that there is a new value-the 8c Avellaneda, and that the 12c Mitre is by now Red instead of Brown.

Except for the change in paper, the various values remained the same. Some values, like the 5c Moreno and 10c Rivadavia Brown, remained on the previous paper. All of the large format stamps (20c Large Cow to 20 pesos) were issued on the new paper. It is difficult sometimes to tell which issue is on a cover, particularly, as is the case for the cover below, if the security paper used for the cover was designed to hide the contents of the letter, and incidentally, a better look at the watermark, or lack thereof, of watermarks for the stamps. The colors of the stamps did not change, however, the unwatermarked frid paper is grayish, whereas the paper used before it, with the first watermark, is cream.

Below is a 1946 cover to the United States, bearing singles of the 2PNGR, 5PNGR, as well as a single 1 peso airmail, and a vertical pair of the new 5c San Martin definitive not part of the 1935-51 definitives series, for a combined rate of 8.10 Pesos.
