Blog of Holding: OD&D Illustrated Wandering Monster Poster
The 18x24 poster contains the complete rules for random dungeon and wilderness encounters in infographic format, and illustrations of every single OD&D White Box monster (200+ monsters), including the rarely-used ones like "thoat," "thoul" and "titanotheres."
Put this on your rec room wall, and you can use it to generate random encounters without having to flip through books, or just stare at it glassily while descending into a spiral of madness.
