i just got back from the "divine comedy" exhibit at the westport arts center. it features drawings from r. crumb and roz chast. i went, primarily, to see the crumb drawings - the roz chast material was a great bonus! i missed seeing the crumb "genesis" exhibit in nyc, so this was in some small way, an act of penance :D
the exhibit runs until may 30, and if you're nearby - check it out. in addition to the drawing, they have a selection of chast's colored eggs on exhibit (and a small sampling of crumb comic book covers). it's well worth the trip!
