The Hyatt Mansion (from an old postcard postmarked 1907), former home of the founder of Hyattsville.
Is this home still standing? If you know, use one of the e-mail links and tell me.
A note about postcards: When postcards were first used, the Post Office wouldn't let people write on the back where the address was, so they had to write on the front with the picture.
