Naval Aviator ID's were presented once training was complete and served as a " pilots license" while in the Navy. They seem to be fairly scarce, even the WWII dated ones.
I will start off with the 1st and best one:
ID Card and wallet to NAVAL AVIATOR # 141 dated 1917. He also earned the Navy Cross in WWI. This is the earliest ID I have seen in private hands, but am hoping someone here on the forum can post an even earlier one.
