Postal History

Flag stamp

First US Flag Stamp

On July 4, 1957, the US Post Office issued its first stamp with the US flag as the central element.  It was also the first stamp printed by the Giori press, which allowed the design to be printed in its natural colors in one step.

ATM stamps

First USPS ATM Stamp

On May 18, 1990, the USPS issued an experimental plastic stamp to test the popularity of selling stamps through Automatic Teller Machines (ATMs). While the plastic stamp proved unpopular, especially with environmentalists, the ATM format proved to be a success.
