ASCII art by Sam Harbison, 1973. It uses a technique called overstriking, when you put characters on top of each other. This was common in typewriter art but was also used on screen for PLATO emoticons. More recently, glitch artists such as Glitchr & Mammifero are interesting examples.
Harbison’s process: 35mm camera -> film -> development -> densitometer -> 9-track magnetic tape -> FORTRAN & EBCDIC -> chain printer with overstriking -> strips of paper -> tape together -> success!
