Via eBay, some real non-AI illustration. Here de-curved and colour-cast corrected (to the extent that’s possible without damaging the picture’s night-time mood). Not also up-scaled. Artwork by Rodell D. Sanford Jr., for what appears to be the first edition of Chaosium’s Lurking Fears RPG adventure anthology (inc. a Florida adventure, which it’s possible the cover depicts).

And another, from 1982, a painting but looking like it’s from the same artist…
