The Met has been displaying the work of a major new artist. Hanging on the wall of its modern art gallery has been a cartoon-style painting of President Bush against a background of shredded dollar bills. A label next to the painting describes it as made out of "acrylic, legal tender and the artist's semen." Charming. Of course, the Met didn't realize it was displaying this work (someone surreptitiously stuck it up on the wall with double-sided tape), but it took them a few days to notice that the rogue painting was hanging there. Three other museums were also unwilling hosts of work by this unknown artist. What I find amusing is the idea of museum visitors standing and nodding as they try to appreciate these odd paintings, thinking they must be the work of some modern master.
