Anybody ever seen this mysterious game before? It was posted on G+, and was found in an Ebay auction, but neither seller or buyer know anything further.
It appears to be a 1981 Heritage mini-game titled
Expedition into the Dungeon, product code 9010.
Three parts: 9010A is the map, 9010B is the 4-page rules, 9010C is the Character/Monster Sheet. The last page of the rules has a Heritage USA 1981 copyright.
The map and rules appear similar to the well-known Crypt of the Sorcerer and Cavern of Doom Paint-and-Play sets of the time:
Dungeon Dwellers Paint'n'Play Sets - Lost Minis WikiBut amazingly I can't find a single reference on the internet to a Heritage "Expedition into the Dungeon".
I checked a 1981 Heritage catalog, and it does have a 9000 series of products, but they are "Boxed Painted Figures" (hand-painted sets of figures from other lines) only go up to 9003.
Perhaps a later (1982?) catalog would have this listed. Was it included in some of the 9000 series sets, or only produced as a promo item...?
