My pen pal and L.W.A. member Joe makes a hobby of sending me postcards with excellent special cancellations. This card and postmark are from the Ben Franklin Post Office in Philadelphia. In addition to everything else he was doing, Ben Franklin was also the first appointed Postmaster General of the United States in 1775. It is fantastic that his original office is still in use today. You can visit it at 316 Market Street, Philadelphia, PA, 19106. Take note that because of the large volume of hand-canceling the office does, they stop accepting mail around 3PM. Remember, "Mail Early in the Day"! Depressingly, and despite its obvious benefit to society, the Franklin Post Office is threatened by the cuts to the U.S.P.S. operations budget, but is currently still in operation. Thanks for the card, Joe. I loved learning about the Franklin Post Office because you sent me interesting mail.
