Up for sale is an 11-piece set of copper cookware from the venerable Brooklyn Copper Cookware company. 
 
Brooklyn Copper Cookware began in 2011 to revive the craft of copper cookware after the original Waldow company went out of business in 1979. They are known for their limited production runs, high-end, handcrafted products, and direct to consumer sales model, which is currently a "selling window" system where they open their online shop only once or twice per year, usually selling out within 48 hours.
 
Purchasing from their website, which is currently all out of stock, this 11-piece set would go for $4,297.
