Roentgen radiographic table and several other new things
A 1906 trade catalogue issued by the James G. Biddle Company of Philadelphia, selling Roentgen radiographic tables and X-ray apparatus to physicians and hospital buyers. Halftone photographs show a suited demonstrator's hands adjusting clamped tube holders, ring stands, and cast-iron tripod bases against plain grey studio backgrounds, offering designers isolated instrument silhouettes and cropped hand-and-machine compositions.
