Keystone View Company Stereoview, Barbed Wire, Fort Sheridan

A Keystone View Company stereoview, number 19860, depicting barbed wire at Fort Sheridan, mounted on cardboard. Keystone was the largest stereoview publisher in the world by the early 20th century, and cards like this one were sold in boxed sets for the parlor stereoscope, part travel entertainment, part visual education, in the decades before radio and film took over that role. Good condition for its age. One piece, one new owner, then closed.
