RTTY babez dating back to the 1960s. RTTY art was around before ASCII was even defined. It uses special keyboards and typewriters to send text messages using radio waves. It was probably used for text graphics already in the 1920s. Instead of ASCII, it (usually) used the Baudot code, which is almost 100 years older than ASCII. All images here taken from the Roy/SAC collection, where you can get both the original data, and a lot of the original photos.
