Buy vintage toys! I recently took a trip down childhood memory lane on ebay and found these beauties. My apologies for swiping these pictures from the original sellers.
First of all, I have fond memories of my Hasbro inch worm ride. If your parents wouldn't buy you a pony, this was the next best thing, and no batteries were necessary. With so many obese kids around today, though, this ride probably wouldn't sustain more than three bounces:
Next, I found a Sit and Spin. Does anyone else remember getting totally sick to your stomach after just a few rotations on this thing? I think today it would make the annual dangerous toy blacklist for causing extreme nausea:
Colorforms rocked! If they got dirty and wouldn't stick after a while, all you had to do was run them under water (or lick them) and they'd be good as new! I had several Peanuts sets including, I'm pretty sure, this one.
Lastly, I found my long lost wooden monkey purely by accident. I was doing a search on eBay for Danish teak furnishes when lo and behold, his old, familiar, geometric face came up. I had no clue that the same spring-jointed chimp that I had as a kid was an Eames era toy. I want my monkey back!
I found all of the items on eBay, but there are numerous resources online for vintage toys; no need to mention where to go to search.
