Do you remember those old "Owl-Master" 3-D viewers? Maybe it was before your time because they pre-date the more common "View-Master" which most people are familiar with.
This, the companies original design, was introduced in the early 60's and of much higher quality, but also very expensive. It was discontinued after the first run due to poor sales and the company soon went bankrupt. However the company re-formed a decade later and went on to mass-produce the cheaper and more popular "View-Master" during the 1970's.
Anyway, I have a lot of fond childhood memories of staring into the eyes of this owl and entering a magical 3-D world. I recently found my old Owl-Master in the attic (still works!) and it inspired me to do this nostalgic design.
