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.
The films were based on attractive scenery, children's stories, travel, night life, and current events.
The company was purchased in 1951 by Sawyer's—the manufacturer of the View-Master—because Tru-Vue had an exclusive contract to make children's filmstrips based on Disney characters.
Competitors of Tru-Vue included the American company Novelview from the 1930s and the British manufacturer Sightseer from the 1950s.
