"This is Your Home" was a popular KNBC show in the late 1940s and 50s. It featured historical San Francisco documentaries written by prolific radio writer Samuel Dickson and narrated by Budd Heyde. Here, Heyde announces one of the programs and cues engineer Russ Butler to fade in a musical bridge. The show was later heard on KNBR under the name "The San Francisco Story.” (Photo courtesy of Caryl Heyde Saunders)
