A new Terror Tales LORA for the Stable Diffusion 1.5 AI. A LORA is a ‘plug-in’ that aims to steer SD’s image generation towards a certain character or type of artwork. In this case the covers of the 1930s Terror Tales pulp magazine. SD is going to mess up the typography, but you could probably cut out the best images and paste onto a template made by vectorising one of the original covers.
Also note the new backdrop generator LORAs Realms of Darkness (generic medieval — streets, castle dungeons, old cemeteries, etc) and Fantasy Underground (generic fantasy) and Fantasy Tavern (generic fantasy). These do look very generic and formula, but you might be able to get something more interesting out of them.
Joschek’s Artstyles: Caspar David Friedrich, possibly useful for eerie sea-views of Innsmouth and its reef. If a full set of Friedrich works was used to train the LORA. Untested by me, as yet.
