ViewMaster own!
When I was a kid I had The Six Million Dollar Man, Bat-Man (lame Adam West version), Space 1999 and many others! I just bought my daughter her first ViewMaster and lots of Winnie the Pooh disks.
On a related note: anyone else remember those movie players made by the ViewMaster people that cartridges with about 10 seconds worth of film in them? I had several Six Million Dollar Man movies for that thing too. Anyone remember what they were called?
(God, I am really dating myself with this post).
