GAF Model H Lighted Stereoscope View-Master (1966-1981)
With instructions and demo reel
I’ve tried one of those I don’t remember where but they are so cool!
@LEGOBastion2007 They were a staple of kids toys for decades, until the 90s really. Before that they were kind of a picture postcard thing where you'd buy reels for places you'd visited and send them to people.
@dgibb01 I wish I could experience the View Master era
