Black and white photograph looking down on a demonstration of a crankshaft during an engineering show. A technician wearing a tie, with shirt sleeves rolled up is operating the machine in the center of the photograph, while another man works on one behind him. The demonstration is being observed by a crowd of spectators, the backs of whose heads can be seen in the foreground, some wearing hats. A sign on the table provides information on the machine and identifies it as display number 13.
