I still have my View-Master. But no slides. To remedy that I bought some brand new Peter Pan slides at Target. It's not quite the same as looking back at the ones from my youth, but it'll do!
I found an AMAZING site that shows the history of this toy. Very cool. Check it out.
I was reminded of this toy when, a few weeks back, I discovered View-Master slides on Bob Logan's blog. Here's a link to all his amazing images which include Huckleberry Hound, Quickdraw McGraw, Yogi Bear.
Logan also links to some super cool View-Master images of the Flintstones on the What My Dad Saw blog. Brian's images MOVE on his site! :)
