Ron Riley was a radio DJ for WLS Chicago from 1960 to 1971. In the mid-1960s, Riley began commentary on the Batman TV show on his radio program, which was soon expanded to create a Batman Fan Club. This button was included as part of the fan club membership package, along with a certificate signed by Riley and Batman and a sticker. The Batman Club became hugely popular, and even resulted with Riley guest-starring on an episode of the Batman TV show.
