This Philatelic Exhibition cover is effectively a first day cover for the complete run of all Argentina 1935-51 values up to the 20 centavos at the time of issue. This cover, with 63 1/2 centavos postage on it, does not represent a recognizable postal rate. Here are quick lines to pages for the three major groups: philatelic exhibition covers, covers that are quite likely philatelic, and covers that seem to represent regular use.

The values on this cover are a complete run. At the time of issue, the Argentina 1935-51 issue comprised nine of the twelve "cents" types, and the 20 centavos "Juan Martin Guemes" (20cJMG).
