Artist: M.C. Escher

Date: February 7 to 17, 1974

"It was here [at Open Space], a former carriage house in the low-rent part of town, that a $1 million exhibition of drawings by M.C. Escher (the 'impossible picture' guy) was mounted, and volunteers spelled each other off sleeping in the gallery so none of the art would be stolen."
