USPS Commemorative Collectibles American Aviation Advances 70 Unposted Stamps.

These were purchased in 2005 at the EAA Air adventure show in Oshkosh, Wisconsin.

The sealed pack contains a total of 50 stamps:  

           there are 2 sheets of 20 stamps,  plus 10  

        unposted stamps affixed  to 10 envelopes, for

         a total of 50.

Plus, one, loose full sheet of 20 unposted

     stamps from a leftover pack.

The package has started to open over time from handling and storage.

You will receive everything exactly as it's pictured.

I'll ship these in a rigid cardboard mailer using first class.
