This show, organized by Stuart Copans, explores some of the dimensions  of collaboration.  The works on display are the results of two artists working together on the same piece, including posters by Mike Dyar of San Francisco, based on postcards he received from Shmuel, a Brattleboro mail artist.  There are collaborative works by Phoebe Wagner and Stu Copans, by Kay Curtis, Ruby Rice, Don Fitzpatrick, Samantha Luk, Ralph Deanna, and many others. Most of the collaborative books, paintings, drawings, and papercuts involve two live artists, but some involve collaborations between a live artist and a deceased one.
