Cover Features Postmarks of First and Last Days of Sale of Pacific '97 Stamp
Two Souvenir Sheets were issued to commemorate the Pacific '97 Stamp Show. Marking the 150th anniversary of America's first postage stamps, the sheets reproduced the designs of US #1 and #2. The stamps were only on sale during the 11-day stamp show - the shortest sale period in US postal history. This cover highlights that historic sale period with a First Day of Issue postmark and a Last Day of Sale postmark. It would be a fun addition to any cover collection.
U.S. #3139 pictures Benjamin Franklin in a reproduction of U.S. #1. The new 50-cent denomination covers the international postcard rate.
