Tru-Vue

Tru-Vue, a subsidiary of Rock Island Bridge and Iron Works, was a manufacturer of stereoscopic filmstrips and corresponding stereoscope viewers, based in Rock Island, Illinois, from 1932 to 1951 and in Beaverton, Oregon, from 1951 until the late 1960s.^[1]

The company is historically significant as a bridge between the stereoscopic cards of the 19th century and the View-Master reels of the mid-20th.^[2]
