Today's Washington City Paper has an article about some legal problems for a couple of artists in the G40 exhibit, but it also mentions in passing that cartoonist Molly Crabapple is in the show. The article's online here, and mostly talks about 'lowbrow' art.
Here's the Post review - "'G40: The Summit' brings art to empty Crystal City space," by Michael O'Sullivan, Washington Post Staff Writer, Friday, March 12, 2010. And details from the Post on the hours:
