Numerous Early Aircraft in Chicago Sky American Air Mail Society 1934 Conv RPPC

Description

Corner and edge wear.  Tips worn, rounded, small creases, fraying.  Soiling.
Hand notated on the back by a collector who claims, as it reads, "1911 card".  To me, it's more likely, with the postmark on the front and the stamp block, its a reproduction of the 1911 World Aviation Meet in Chicago, with the 1930s stamp block.  Or, a 'cut and paste' job made up just for this big Air Mail Society Convention.  They seem to have their own postmark for the event.
