Details For Cover ID# 27260

Non-carrier drop letter, 3c rate paid by 3c Statue of Liberty sheet stamp. Addressee had moved out of the drop rate area (to a new city: Wichita Falls, TX)and left a forwarding address with local PO, so mailing PO marked it as "1c Due" in blue pencil at left of 3c stamp and held it for the extra 1c postage. It should have been forwarded as a postage due item to the delivery PO; instead, in a very unusual procedure, the mailing PO notified the sender for payment. It was then forwarded to the addressee after a 1c stamp was placed over the blue due notation to make up the 4c per oz domestic first-class letter rate.
