TOD
I never knew from Colorforms! I shall have to ask my sister if she had them.
Off the top of my head (which neither holds nor sprouts anything), I'm remembering an electric train set, a little set of toy soldiers, a couple of chemistry sets, a (Sears, I think) gas station, a toy steering wheel and dashboard thing, and... and... what else? Interesting question. I'll have to think about this. I know I was crazy about toys, and the fabulous toy department at the wonderful downtown Lazarus department store at Christmas, but what the HELL were they?
Oh yes, View-Masters. Yes indeed. We had some, and my grandparents had some, plus one of those viewers with the battery-operated light attachment. About ten years ago I developed a renewed interest in View-Master and bought a couple of viewers and some reels off eBay. Probably none of the real rare and collectible ones, but a nice little selection. There is, or was, a woman in Cincinnati who had the biggest, rarest collection of all things View-Master; my folks sent me an article about her. I do love that stuff, and would also not mind having a collection of the old stereo-optic cards (what's the proper name for them?) from around the turn of the last century, but I've never made a move on that.
