1.5" litho without maker name has just the slightest hairline dent at upper right but still displays Mint. This character was created by television personality Pat McCormick while working at ABC-TV in Los Angeles in 1959. The horse character was inspired by Dennis Weaver's character Chester on the TV western Gunsmoke. Charley was a horse who wore a sea captain's hat while his partner Humphrey Hambone was a bulldog. The characters followed McCormick when he signed on with San Fransisco's KGO-TV in 1961 which was the "Channel Seven" station as designated on this button. Limited distribution and rare.
