I'm pretty new to the blogging scene, so, be gentle... I'm in the process of boxing up everything in my mother's home & moving it here to Champaign. I have ran across quite a few things that I think are very cool & that would fall into the "Design" category. This old "3d" viewer is one of them. The way that it takes 2 pictures on a card & combines them in such a way that when viewed through the "viewer"  makes the image look 3d. It is such a cool thing that I'm going to keep it to pass down to my son. It has a dozen different cards with it & I'm hoping to find others on-line to add to my collection. I find these to be in the Graphic Design category because all of the cards are like mini advertisements. They all have the name & place listed on the back of them, along with the year, photographer name & any copyright information.
