When I found this wonderful items I had to do some research. Looks like it has never been used, this armed forces stationery is a pack that is given to all military to write home with. This individual one is from the 64th Fighter Interceptor Squadron with the address of Seattle, Washington. In 1941 this tactic group flew with the Northeast Defense Sector, the Cold War, and Vietnam. This pack is full with letter head sheets and back sheets plus all the envelopes you would need with return address of Seattle, Washington. Even the folder is in excellent condition.
