A backstage view of Washington, D.C., inventor George Coleman’s “Lifelike Baseball Scoreboard” (seen earlier here and here), which was set up in movie theaters to “broadcast” the home team’s away games. “It contains 19,000 feet of wire and has 400 stereopticon slides with an electric light bulb for each slide.
