I had this particular View Master disc when I was a kid. I just found it via the Drawn website but when I followed the link I found the whole series of images in a form that mimics the 3D effect. You can see those images here.
I still have my View Master. It's in a box somewhere. I have some discs too but I'm not sure the Flintstones is one of them. I'll have to pull them out and see what I've got.
