The 30c clay paper on cover

This stamp is somewhat rare and always a good find on cover. This first cover bears only clay stamps: the 10cBR and the 1 peso are also clay paper stamps.









This 2 peso cover has a 30c clay stamp late in use (1945).











This philatelic cover from 1958 also bears a 30c clay stamp.



Here is the receipt for the stamps sent with this envelope to a collector.
