Viewmaster

Although not commonly associated with the stereopticons, the View-Master uses a similar type of technology to produce three-dimensional images. The View-Master was introduced in 1939 by the Portland-based Sawyer’s Inc. Today the View-Master is owned by Mattel and is in the US’ National Toy Hall of Fame. This particular viewmaster reel is of a variety of different types of mushroom and is housed in the Rare Book Collection.
