Dungeon Geomorphs Set One to Three

From the front cover:

This new booklet is a combination of the original three sets of Dungeon Geomorphs released by TSR The Game Wards: Basic Dungeon, Caves & Caverns, and Lower Dungeons. It contains 30 square geomorphic pieces and 15 rectangular semi-geomorphic pieces that are ready to cut out and use. With only 4 of the 45 units contained in this product, Dungeon Masters can form hundreds of thousands of maps in mere seconds! No longer will a Dungeon Master be forced to spend hours upon hours drawing a dungeon level that plays through in one session - with these geomorphs DUNGEONS & DRAGONS Fantasy Adventure Game players can look forward to infinite variety even though they may play more often.
