Six photos, glossy and satin-finish, ranging in size from 3.5 x 4.75 to 7.75 x 10, each signed by a notable cardiac surgeon or scientist, including: Christiaan Barnard (3), Denton Cooley, Michael DeBakey (ins), and Robert Jarvik. In overall very good to fine condition, with some creasing and irregular toning to one of the Barnard photos.
