This awesome vintage toy zoo from Germany fits into eight beautifully designed matchboxes. The pieces are so small, you have to wonder if they might actually not even be a choke hazard; just wash'em down with an extra bottle.

I had (still have, somewhere - it's long been a favorite) a set of these that had an igloo, polar bear, penguin ... and some sort of U-shaped piece, I think it was. I got it at a zoo - maybe San Diego?
Now you've motivated me to go digging thru the basement to try and find it. As I remember, the box has pretty much disintegrated, and I lost a piece or two, but I hung on to it for a long time - I always thought it was damn cool.
Holy Crud! I have the camel set somewhere...with box intact...given to me for some long ago xmas. I think my brother had the kangaroos. Awwwww...
No idea they were part of some larger, not so inexpensive, set.
I imagine they weren't so expensive back in the day.
