Mike Mitchell (20)

Largely because Mike is considered an unknown photographer, the story is that Mike took a bunch of pictures way early on in his career—he was just eighteen at the time—of the Beatles, in one of their very first U.S. appearances, at the old Washington Coliseum, in February of '64. Each of Mike's Beatles pictures is an edition of one—that's right. Each print is unique. 46 prints were auctioned off at Christie's New York store on July 20th—and realized $361,938 inclusive of commissions.
