1945 WW2 Soldier Peeling Potatoes Postcard

"Now I know what they mean by K.P. ... Keep Peelin' " vintage comic postcard. The 1945 postmark is accompanied by a World War 2 Postage FREE on this vintage postcard. Servicemen enjoyed free postage throughout the war. All a soldier or sailor had to do was write “Free” on the piece and the Post Office would deliver it. Even if a soldier wanted to mail the end of a C rations box as a postcard, the Post Office would deliver it free of charge. Mailed from Fort Riley.
