Although this postcard is a highly stylized, artificially colorized depiction of the NBC Radio City studios at Sunset Blvd and Vine St in Hollywood, it gives us an idea of the sort or artwork / photography hybrid they used to produce in the 1930s. The building went up in the late 1930s so I’m guessing this was a promotional postcard to publicize the opening. Look how short those palm trees were!
