This is another Transport cover that I acquire from the recent Nutmeg auction. This cover to South America is franked with two 10-cent Transports C27, with 5/7/1945 duplex cancels tie with a 5-cent Prexie, addressed to Bogota, Columbia. It is returned to sender, censored, Universal Institute corner and 3 colorful backstamps. A very attractive postal history.

What is interesting about this cover was, the 25c rate to Colombia was by far the most brief usage during the 1941-1946 period to the South America continent according to the GH Davis Transport handbook. It would be quite a challenge to go out and look for an example of this. Do let me know if you find any!
