Just did some digging, and it's legit and from a 1994 book called "The Internet Guide for New Users" by Daniel P. Dern.
Mildly interesting side-note, I found someone's blog about posting this image and book to a (now non-existent) fediverse server. https://doughnut.neocities.org/blag/15
It's so sad. I feel like we need to be hoarding all sorts of random media that was put out pre-AI, because it's flooding everything. Videos, music, gaming, historical photos/videos...
Random example: I have a folder of desktop wallpapers that I've been casually adding to for the last decade or so. Literally thousands of them by this point, but I haven't added anything recently because every source is inundated with AI generations now.
