America's top gumshoes are back to prove once again that an object found in an attic or backyard might be anything but ordinary. Wesley Cowan, independent appraiser and auctioneer; Gwendolyn Wright, historian and professor of architecture, Columbia University; Elyse Luray, independent appraiser and expert in art history; Dr. Eduardo Pagán, professor of history and American studies at Arizona State University; and Tukufu Zuberi, professor of sociology and the director of the Center for Africana Studies at the University of Pennsylvania leave no stone unturned as they travel around the country to explore the stories behind local folklore, prominent figures and family legends.
