Annie - That photo has been mislabeled by the original photo printer. That name legend was added during one of the printing processes. In other photos taken of that same group the label covers a banner that read "N.Y. World" as in the newspaper. That man sitting on the box is Major Burke, he's seen in several other photos taken on about the same day. Burke had some significant management capacity with Buffalo Bill's Show. I've read that he had traveled with B.B. as part of his staff, in B.B.'s personal railroad car, to the Rosebud Reservation prior to Sitting Bull being murdered. B.B. had been requested by the Army to personally ask and escort Sitting Bull to surrender himself to the Reservation. B.B. had a previous close or working relationship with the Chief and it was felt that only someone like B.B. could bring the Great Chief in without war breaking out.
