I know that's a blurry, generally crappy photo, but come on! The One-trick Wizard & the Egg? Best name of a thing ever. One-trick wizard. I love it.
The rest of these, probably James' and my favorites in the museum, are by Frances Jetter. I stopped reading the accompanying notes when I got to the part about the eraser being a symbol for censorship - I much prefer the sense of a giant eraser monster coming to attack pencil drawing people, an eraser being a pencil drawing's ultimate fear, and leaving it at that.
(Ms. Jetter's own, and better, photographs are here.)
