Original QSL postcard from the mid to late 1960s.This used card, postmarked 1967, was sent from CB radio station: KQD-5091. Was issued to Lynne and Jerry Beyer, at 217a East Marshall Street, San Gabriel, California. The family dog name was Ralph. Card is white with red text. Partial postmark bled through picture side. During the 1920s and 1930s, amateur ham radio operators adopted the practice of two-way exchanging of QSL postcards, to confirm their radio contact, with a report of reception. QSL cards got to be known as wallpaper, commonly used to decorate the walls of their radio equipment room. During the 1960s, CB citizen band radio became popular, and the practice of exchanging QSL cards to confirm radio contacts was enjoyed by many with this new hobby. Today, these cards are very collectible and look great matted and framed.
