My guess is it was a figure in this article: https://www.computer.org/csdl/magazine/an/1988/04/man1988040...
Edit: Confirmed, kind of. A similar but different picture is figure 9: https://www.semanticscholar.org/paper/A-Historical-Overview-...
It looks like the picture slated for figure 11, that made it to the CHM archives, didn't actually end up in the article.
