The device itself hails from 1939. I do not know the date of the ad. 50s? 60s? Probably no earlier than 60’s per deduction from everett@lemmy.ml below.
It seems like the projector version, you would lose the 3D, wouldn’t you? Which is the whole point of a Viewmaster, for my money!
I like this ad style too.
They could’ve done color-based 3D with cheap movie-theater paper glasses.
No idea if they did though, would probably require a different set of reels.
Not sure what you mean, Viewmaster was in color.
Viewmaster reels looked awesome, though. Anaglyph 3D, not so much.
