Tell stories the way we did in the old dem days: through a lavishly painted advertisement for an awesome conglomeration of media and merchandise, trained on the styles of a plethora of 1980s kids' book largess.

Helpful Notes:
(Most) Characters are tagged (too many to list) but few to the point where they can be faithfully replicated, should be enough to help genre-match if you've got an accompanying LORA.
Cat anthros and associated characters will take on Thundercatian traits, negative prompt Thundercats to correct this. selectively prompting/negative prompting the series and genre tags should help you tune in if you have a specific look in mind.
Should work in any orientation (I , but square does the best given the training data).
