(CBS News) — Bernard Kinsey is a collector – and a storyteller. Get him started and he can’t stop. His converted wine cellar is filled with fine, vintage African Americana, reports CBS News correspondent Bill Whitaker. “This stuff is not only valuable, it’s really rare,” Kinsey said. It’s a passion he shares with Shirley, his wife of 43 years. “I buy the dead artists, she buys the living artists,” Bernard Kinsey said. The retired Xerox executives collected for four decades, until their L.A. house was bursting.
