Here’s one I hadn’t heard of until I saw it recently. Advanced Dungeons & Dragons: Role Playing Dioramas(NSI, 1983) is related to those wood burning kits that were the rage back in the Eighties. NSI in fact still makes those sets.
This diorama set was officially licensed from TSR, complete with the angular logo on the box.
My particular set for sale: Box is square, with moderate wear. All 12 figures present, and colored by former owner. 11/12 bases present. All the weapons appear present. Also contains the 3 art backdrops, gemstones, even the mostly-dry pens and completely dry glue container, as well as the cedar wood slats. No instruction sheet.
