On August 28, 1934, the Post Office Department issued U.S. #750 as a souvenir sheet in conjunction with the American Philatelic Society’s Convention and Exhibition being held in Atlantic City. The sheet contained six 3¢ stamps featuring the breathtaking beauty of Mt. Rainier. This stamp was just one of ten printed by the postal service that year for its National Parks series. U.S. #750 was produced on 120-subject plates, with 20 panes of six stamps each.
