I don't use AD&D-style bugbears. I use the bugbears I made up for GURPS Dungeon Fantasy Monsters 1 - boogeymen-like stalkers who choke and club and murder.
But I just love this picture of Bugbears from David Trampier in D1 / D1-2:
I'm re-reading D1, D2 (and D1-2) and D3 to review them, and it brought back how much I love the artwork in them. That piece especially. It makes me kind of wish I had used AD&D bugbears, so I could use that picture for them.
