Original QSL postcard from the mid to late 1960s.This unused card was sent from CB radio station: KPA-3774. Was issued to James E. Avery, of Soledad, California. Base and mobile units. Card is white and orange text. Includes a second card of James Avery, not shown. Card is burnt orange color with black text, a different type of paper, and was stored next to this card for several decades, and foxed the card, due to acid content in the paper. 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.
