Post Office Department poster in red, green and black ink on a white background reads "Beautify Your Christmas Cards with Christmas Stamps Mail Early" and includes a black and white reproduction of the first US postage stamp with a Christmas design, featuring a holly wreath and candles.
The Post Office Department’s public service advertisement poster released in August 1966 promoted ZIP code use. It featured Mr. ZIP with his iconic letter carrier’s uniform and satchel. Unlike advertising a new service or announcing a regulation, bringing ZIP codes to the public’s attention centered on the difficult task of changing people’s behavior.
