The kids have loved looking into these nostalgic stereo viewers!
View-Master's history begins in the 1930's when William Gruber created a camera for taking special stereoscopic photographs, then designed a hand-held viewer for viewing them. The idea was initially intended for adult educational purposes, but evolved into becoming a well known form of entertainment for all ages. The interchangeable slides gives us a glimpse into different places and times in a realistic, three-dimensional way---an old school approach to augmented reality.
