I have a lamenated ten cent postage stamp from Asheville, N.C. dated August 26-28, 1937. Plate # 21696. In Compliment To The 43rd Annual Convention Of The Society Of Philatelic Americans. Printed By The Treasury Department, Bureau Of Engraving And Printing. Under The Authority Of James A. Farley, Postmaster General.
I know an upside down stamp means I love you.
What do the other positions mean? Straight up tipped to the right? the left? On it’s side? There’s lots more. I know it’s popular with inmates in prison.
