Business size 8.5" x 11" envelope showing front and back of the AMERICAN MOTORCYCLES STAMP SERIES FIRST DAY of ISSUE 2006 Sturgis SD Pane with the scarce Motorcycle cancel. From a non-smoking and pet/scent free home. Envelopes are in pristine condition, unsealed. Up for sale are two (2) envelopes! The price is for both envelopes. I will pack them in a bigger envelope with cardboard so the postage is a bit of an expense but these are fun! Thank you.
