The Brumberger was manufactured by Brumberger Sales Corporation of Brooklyn, New York in the 1960s. The viewer was plastic and used two ‘D’ sized batteries. It was also focusable by means of a thumb-wheel. Underneath was a mounting point for a stand. The viewer was turned on by depressing a round button, on top of the viewer that carries the Brumberger little man logo.
