The original Disney-produced TV series Zorro (starring Guy Williams) ran from 1957-59, but a decade after its debut on ABC it still had life in reruns. This ad for the show ran in 1967 and shows us that it was airing on WKYT-TV (channel 27) out of Lexington, Kentucky. The station started out as a CBS affiliate, switched to ABC in 1958, and moved back to CBS in 1968.
