Notes: The first Horn and Hardart Automat opened June 12, 1902 at 818 Chestnut Street in Philadelphia, PA. The first Automat in New York City opened 10 years later at 1557 Broadway, Times Square, between 46th & 47th Streets.

A 1921 ad in Plant-Restaurant Management for The Stearnes Company in Chicago touts its outfitting of "Horn & Hardart's new Automat and Cafeteria on Sheridan Road near Wilson Avenue, Chicago." And Jan Whitaker, writing in a September 8, 2019 piece for her Restaurant-ing through history, confirms the presence of two Horn & Hardarts operating in Chicago in 1922.

While not topmarked specifically for Horn & Hardart, a Horn & Hardart brochure in the collection of the New York Public Library shows the same "Automat" typography as that used on the platter. The burgundy backstamp on the platter would date its use into the 19th century, but we're using the 1902 year as the first possible date it could have been used since that's when the first automat opened.
