Talking Pictures in Color!
Here’s a great article from 1929 about radio—with pictures! A test (with a pretty girl as the test subject, of course) is performed at Bell Telephone Laboratories in New York City.
A VERY pretty girl in a fancy dress of many colors sat before a transmitter in a certain section of the Bell Telephone Laboratories in New York City the other Jay. Just a few steps away, in an adjacent room, a group of famous scientists and journalists, evincing the utmost curiosity, concentrated their attention upon a television receiving apparatus.
Their interest was soon rewarded. Sweeping across a large magnifying lens, connected with one of the most modern types of radiovisor, could be plainly seen the dress, features and form of the charming girl, in the original colors!
