Sound & Paper

QSL cards are personalized postcards that were used as a record of contact between CB radio (and other two-way radio) operators. Think of them as a proto-internet, a social network made of sound and paper. They are a little bit postcard, a little bit cartoon, a little bit mail art, a little bit folk art, a little bit outsider/naive art, a little bit ephemera.
