1.25" from 1938 by Phila. Badge complete with their backpaper. Button reads "Flash Gordon Adventure Club" issued to promote Universal Pictures 12-chapter serial "Flash Gordon Conquers The Universe" starring Buster Crabbe and Carol Hughes, both pictured. Button's bw center area has light tan tone showing slightly on Flash's face and in the "V" neck area of Dale's costume. The cello also has much extremely fine scratching, mostly on upper half but not deep and not even that noticeable in reflected light. With normal viewing, the bit of stain shows but not the scratching. Overall Fine. Our first to offer in years. Out of a 40 year collection. About third we've seen.
