Issues of 1948, 1949, and 1950
| These years represent three change in watermark and paper. The first paper ahs the second watermark-the "2" issue, the second paper is unwatermarked, now opaque instead of gridded, and the third paper is on a clay paper similar to the one used for the typographed 1c Sarmiento, 5c Moreno, and 10c Rivadavia Brown during World War II. The "2" issue, is printed on a bright white and thick paper that feels like fine sand paper to the touch. This second watermark is notoriously difficult to tell apart from the first one for the small format stamps, as shown below left, and is somewhat easier to identify for the large format values, as shown below right. The new watermark has longer, straight lines joining the RA in circle. | |

The "2" paper makes for clearer, crispier designs. Compare the 30c2 below to its 30c1E1 counterpart below it. Notice that I have placed a 1 after the 30c1E designation: there are several distinct printings for the 30c between 1936 and 1944, and the one illustrated here is from the first printing. These 30c1E1 stamps are printed on cream paper, and have distinct colors. The later issues, 30c1E2, and 30c1E3, have different colors and are printed on a paper that is light cream. |

I follow the same comparison procedure I used with the 30c Lanas in the case of the 2 pesos Fruticultura. Immediately below is a gorgeous 2P2 on piece, accompanied by a 30c2 and a 10 pesos that is most likely a 10P1E. Below the piece, is a 2P1E, which, unlike the 30c value, was printed in one combination of colors and paper. |

| Below are two values printed on unwatermarked opaque paper. These issues are often found with comb-like perforations, as is the case for the 1 pesos shown below left. The 5 pesos NOP, however, has crisp perforations, bright and distinctive colors, and a crisp image, as shown below right. | |

| Below are two specimens from the clay paper printing; a 2 pesos, and a 20 pesos. | |
