Remember the TV test patterns? They came on at night after a formal sign off by the television station and the National Anthem. They were used for adjusting the receiver controls for optimum reception.
In 1949, television programming was only a few hours a night and the test pattern replaced the shows. The most famous design was the "Indian Head." It was designed for RCA by an artist named Brooks in 1939. The original artwork was found in a dumpster by a wrecking crew worker. He saved them for over 30 years and sold the art to a test pattern collector.
The "Indian Head" pattern was built into an RCA monoscope tube which acted as a replacement for a television camera. Many of these tubes were saved as souvenirs and art pieces. But, nearly all of these small, hard to open tubes were junked. The actual cards, on the other hand, were 1.5 feet x 2 feet and saved for wall displays.
There is a great little blurb on Cheech and Chongs album, Big Bambu. Cheech drops by Chongs pad and asks him what he is watching on TV. Chong replies, "I don't know, it's a movie about Indians, but it's really boring." Cheech says, "Hey man, that's not a movie, man. That's a test pattern, man." Chong answers, "Far out!"
