I’m going to go ahead and call these drawings masterpieces on par with the Orvis’s illustrations of Disney’s The Black Hole. They’re from Stefan’s Flickr, and there are 91 glorious pieces, all of them perfectly captioned, in his D&D Pencil Art album.
Note the soda machine that has fallen through a “dimensional rift” into D&D world, as well as the bank robbery (“we were low on GP,” says Stefan). Other art not featured here includes a decapitating ninja, a “giant robot warrior machine” shooting down an X-Wing Fighter, an “Apocalypse Arena,” an arm-wrestling dragon, a Sumo warrior, a wizard on a magic carpet dueling a giant eagle, and a bitch-slapping grizzly bear.
The set belongs in a museum.

The big monster in the last picture is Zargon, the boss in the module B4 The Lost City
Brilliant. I love that hand poking out of the water. Its owner chose jewels over vigilance and the safety of the party. A powerful statement against selfishness and greed!
