Ritz Tower, NYC, New York
Historic Postcard from NY Public Library Digital Gallery
Undated postcard but must be mid-to-late 1920s. I’m not positive, but Google Street View makes it looks as though the building is still there — at or near 57th St. & 5th Ave. It’s got a rather distinctive, narrow shape with little ornaments.
Note: Prepare for an onslaught of NYC pictures. I started in on the NYPL archives and there was much to share!
