I’m quite familiar with Charles W Soulas steins advertising the Rathskeller in Philadelphia which was opened in the late 1800’s. However, I have a stein that says, “Imported Beer Gus A Soulas, Original Rathskeller 22-26 S 5th Street, Phila”. I tried to research it and could not find anything about Gus Soulas owning a Rathskeller there. I did find a listing for a Gustave Soulas being born in Philadelphia in 1926, so maybe this was a grandson? Anyone here have any information on it?
