This week on MARKET WARRIORS, pickers Miller, John, Bob and Kevin head to the Midwest for one of the largest shows in the region, the Springfield Extravaganza in Springfield, Ohio. Once there, the pickers are challenged to sift through the 2,000 vendors to find the best piece of cast iron to sell at auction. Some unique picks include a Jazzboy Jim toy, a Salvador Dali lithograph and a pair of chairs made of skis. Their finds are auctioned at A.N. Abell Auction Company in Los Angeles.
