There is a wonderful exhibition at The Morgan Library called “Drawing Surrealism” (http://www.themorgan.org/exhibitions/exhibition.asp?id=70) that is full of interesting stuff–automatic drawing and painting, decalomania, inkblots, collage–all works on paper, very inspiring. The show is up til April 21st and is excellent.
