At the Battle of Antietam in September 1862, the first true images of war were produced by photographer Alexander Gardner using a stereo camera. Gardner's images were put on display at Mathew Brady's Gallery in New York City. The public was shocked by the reality of the photographs. Newspapers of the day were unable to reproduce photographs and relied on artists' woodcuts which were published in papers like Harper's Weekly. Enterprising showmen produced traveling exhibits to tour in the North. Such a program was scheduled for presentation in Warren on Feb. 27 and 28 at Webb's Hall on Main Street.
