Not sure if this is the right place...
I would need no help in compiling a list of chess movies or even chess literature scenes. Comics, though, are a more fleeting medium, and here a list would be much harder to come by. (Obviously I googled beforehand, a bit has been done already.) I prefer examples with actual plot relevance, though, and with actual valid chess. (E.g. Prince Valiant pulling the good old stalemate-with-living-pieces defense.) The obscurer, the merrier.
But specifically (and that's my real question), for 40 years I'm looking for the source of:
a) a Mickey and Goofy adventure. They have to solve a chess problem. Goofy being Goofy inadvertently misplaced a piece, leading to a wrong solution and the good old ACME trapdoor.
b) a SF in a B/W magazine (Eerie or Creepy would be my first guess), where chess is never even mentioned, but as a FM, I immediately recognized the spaceship formations as executing a smothered mate (metaphorical plot relevance alert!).
