Vanity Fair has a lengthy, fascinating article on the travels of Zeke Schein, a guitar aficionado who found a photo purporting to be of B.B. King while trawling eBay one day–and realized that the photo definitely wasn’t of King, but may have been a rare shot of famed bluesman Robert Johnson. (There are only two verified photos of Johnson still around today.) The picture led Schein on a two-year journey of research into the life of the man, one that inspired VF writer Frank DiGiacomo on his own quest to figure out who was in the photograph. The question of whether the photograph is 100% really one of Johnson is never answered, but that doesn’t make DiGiacomo’s piece any less satisfying. [Vanity Fair]
