Back in the day, 1985 or so, Adobe had an example PostScript file, golfer.ps. It was generated using Illustrator by tracing over an original line art. The original artist took offense and it was removed from circulation and replaced by another golfer line art [1]. FWIW, the lenna[2] image was scanned from a Playboy and the Utah teapot [3] was modeled on a Melitta. Are there any copies of the original golfer.ps on the internet? It was black and white line art with no gray scale.[1] https://upload.wikimedia.org/wikipedia/commons/8/8a/Ghostscript_golfer.svg
