I don't know if anyone is interested, but DiverseWorks in Houston is having their second annual summer luck of the draw art auction a week from today, June 18. $100 gets you in the door, wine and beer, and you get a number for the drawing. Your number gets picked, you go to the wall, pick out your art, and take it home. I think that there are about 200 pieces of art that have been donated so far, and DiverseWorks events are always a lot of fun. It's an inexpensive way to add to an art collection, plus the money goes to an excellent organization.
