View of part of the main hall of the Universal Exhibition of 1867, Paris. The collector's label pasted on the back suggests that it is an amateur view mounted on a card originally produced by the American Stereoscopic Co., and that it shows an exhibition of armaments being installed or removed. It actually seems to show non-military machinery. Title written in ink looks almost like "Paris Exposition 1864," which is a dating error.
