A STEREOGRAPHIC IMAGE OF AN AMERICAN WW1 OBSERVATION BALLOON
A STEREOGRAPHIC IMAGE OF AN AMERICAN WW1 OBSERVATION BALLOON
A stereographic image of an American observation balloon in use during WW1. The verso bears a lengthy and evocative description of the balloon and its use as a tool to monitor German assets and movements. Stereograph images are meant to be used with a stereoscope, a device in which you slot a stereograph and then hold up to your eyes almost like a pair of binoculars, giving the image a sort of three-dimensional effect because of the slight difference in the angle of each photograph.
3 1/2 x 7 1/4 in., (6.4 x 18.4 cm.)
Condition: Very good overall, board slightly warped, some minor discoloration towards top of image.
