These beautiful ceramic spray cans are the work of Carrie Reichardt, also known as The Baroness. Reichardt's ceramic spray cans feature tongue-in-cheek social commentary; for example, the pieces in the second image say, "Just my f*cking luck, capitalism collapses as my work hits the art market." The spray cans in the third image say simply, "Work. Consume. Die."
Carrie Reichardt's ceramic spray cans are frequently up for auction; the "Work. Consume. Die" spray cans are currently being sold at Auction Saboteur.
