Real 1950's era coin operated amusement devises. Seriously lame! put a dime in one of these things and act like a fool and see yourself on a camera attached to a TV screen monitor. See yourself in living black and white. Or hear your voice over the long distance phone with an echo. I'm glad I grew up in an era that I could use my very own camcorder as a kid and see myself on TV and in color! Yes, I guess this was a huge novelty back then.
