This Tru-Vue 3-D Viewer from the 1950's is designed to view rectangular 3-D cards of color picture stories. The viewer comes in its original box (which has some surface damage). The box loudly proclaims that this viewer is "The happiest invention since a child's laughter"! The sturdy plastic viewer has a smoothly-working mechanism. The body of the viewer is marked Tru-Vue Company Beaverton, Oregon Pat. Pending Made in USA. There is design patent number 171049 on the body of the viewer. The eye pieces and the front lenses are clear and without scratches. The white specs that show up on the images of the viewer are tiny specks of dust (how embarrassing!) I don't have any cards for this viewer, sadly.
This is a consignment item.
