Camera obscura constructed of walnut and has butt joints and dovetail joints (inner box) and a wooden lens surround which is an indication that it may be quite early, possibly pre-photographic, before 1839. With ground glass and angled mirror. The country of origin of this camera obscura is unknown, but likely English or American. The attention to detail is evident in the wooden cover for the door hinges, the wood molding securing the ground glass, the indentations in the sides to facilitate sliding out the inner box, and the door closing latch. Size 5 1/4 in. wide by 3 3/4 in. high by 8 1/2 in. deep (closed) and 10 1/4 in. deep (open). The viewing glass measures 3 x 4 1/2 in.
