Many of these were photographed at the McClees' studio, which later offered the portraits in bound volumes and as separately mounted prints. Each image was 6 1/2 x 8 1/2 in., and could be ordered hand-colored by the studio artists, Messrs Aubert and Kerchove. The bound volume of portraits was entitled North American Indians Taken From Life.
