This souvenir card was in my father-in-law's stamp collection.  We know little about it except that it was issued in August 1972 to commemorate the inauguration of the USPS.  It has always been in a dry, smoke-free home with no pets.

Please look carefully at the photo as it is part of the description.  Card has corner dings.

Card will be protected by a file folder or something equally stiff and mailed in a 6 x 9" envelope via First Class USPS within two business days of receipt of payment.
