Aaron Westerberg announced a sale on his 'small works', this morning. Below, are the remaining pieces available for purchase. I think 'Pink Coat Study', 'Cutting Study', 'Bathroom Study' and 'Malo Sketch' are the pieces to purchase, if you're looking for your next original. Pieces range from $300-700.
