This week on MARKET WARRIORS, pickers Miller, John, Bob and Kevin head to the Brimfield, Massachusetts, home of the largest outdoor market in the world. The pickers struggle to find the right items to sell at Cowan's Auction in Cincinnati, Ohio. As part of the challenge this week, the pickers are teamed up and tasked with finding art glass among the market's 6,000 vendors. Some notable picks include examples of Bohemian art glass, a vintage scale and a handmade dollhouse.
