One of my favorite stamps issued by the USPS have been the 1976 Bicentennial Souvenir Sheets. I was able to acquire these sheet for around $8.00 off of
ebay last year and I just love staring at them.
I'm not sure what the print run was of these things, but I always have thought these stamps should never actually be used as postage.
So, my Minuteman 2003 and 2004 supplements I won off of
ebay came in the mail today, and the stamps the guy used on the envelope were all the bicentennial souvenir sheet stamps. If I had known, I would have offered to buy the sheets from him.
Ah well....
