One of the biggest and best art sales of the year, the annual Art 4 Shelter benefit for Simpson Housing Services returns with over 1,000 original pieces of art on paper with the artists’ names hidden on the back, so you’ll end up with a nice little collectible from either someone up-and-coming or surprise big name. And you will likely grab something, since the 5″ x 7″ works are only $35 each and the 8″ x 10″s are $90. Wednesday, May 15th, 6-9 PM. Free.Tracy Oxford
