I got these from a car boot sale in Cornwall four or five years ago. I probably paid 50p to £1 each, a bargain at the time and nothing has changed in my mind. Each one has a happy face on one side and a sad face on the other. One had a white plastic collar a bit like a medieval ruff when I bought them but it was too big and had been glued badly. I removed it and I don't believe it was original to the toys but I could be wrong. It didn't look right but I probably still have it in a box somewhere? I'm guessing 1950's or 60s's and there are probably others in the 'set' but i've never seen any others since.
