Monster Brains posted GIANT scans of the 1979 D&D coloring book here. I had never seen this before as a kid and probably would have ignored it. Who would spend 10$ on a coloring book when you could spend $12 on a new hardback monster manual 2 or Oriental Adventures (I never owned the latter)? The art really quite good, but it’s not Tramp or anything like that. If you have kids, these are easily large enough to print out on 8 1/2 X 11 and set them to coloring like the slavemaster you are.
While never into the whole Old School revival (of D&D at least), this is a gem.
