Back in the 1990s, the names of cartoonists like Chris Ware and Dan Clowes were fringey talismans of cool. Dash Shaw is the modern equivalent of those cartoonists. His comics, especially the epic Bottomless Belly Button, are pushing comics forward at a pace that no other artist is approaching. Shaw’s artwork will be on display at Fantagraphics Bookstore from April 13 through May 8, but tonight Shaw will be in attendance to screen his new animated short Seraph. This is your chance to be in on an “I-knew-him-when” kind of moment.
