This location of the Provident Loan Society at 7th Avenue and 49th Street is either lost or hidden behind massive billboards at Times Square. The building that exists there currently was built c. 1920 and there are photographs of this building of the Society up to 1915 at the Museum of City of New York. The current structure has four floors however, so either the old structure was expanded or demolished completely by the 1920s. Today, the building hosts Ray’s Pizza and other businesses on the ground floor.
