I wish i had kept all of my old dungeons from when I was a kid / teenager, but alas, most are long gone and probably best forgotten.
I did find this "One-Sheet", if you will, with a dungeon map on front and the keyed locations on the back.
Who needed anything but number of monsters, loot and possible traps when writing up your dungeon? Anything else is just taking up wasted space.
At least I didn't use every single square on the graph paper for the dungeon - there was some actual space being used to keep it all from falling in on itself.
I'm going to guess circe 1983 or so - earlier and I wouldn't have left any free space on the map and much later I would be including "Dungeon Privies", "Air Vents" and "Waste Disposal Chutes".
Still, I notice there is little rhyme or reason as to why this assortment of creatures would be in a dungeon, let alone why they aren't dying off from lack of food (apparently I did include a dungeon stream, which provides water AND is where I place 5 Giant Crocodiles).
Ah, the good old days, when "It just is" was the answer to the rarely spoken question: "How the fuck did all this stuff get in here in the first place?"
