Alternate title: "The Blob." Washington, D.C., circa 1919. This glass negative is in sad shape but still has lots of interesting details, especially if you're a movie buff. A very indistinct scrawl along the edge has been transcribed as "Meadus Theater." Extra credit for the first commenter to Street View this. (UPDATE: Put your hands together for Charlene, who was the first to correctly name and locate this cinema -- Meader's Theater on Eighth Street S.E.) View full size.
