I bought this clock for 20p.
A clock is always good to have and can be put in almost any environment, and one of my current projects is a clockmaker's shop, so it came handy. I thought I'd paint and varnish it. Now I am glad I took a closer look before I did. This is what I found on the back:
You cannot see it very well in the picture, but it says © LOUIS MARX & CO, INC MCMLXIV.
It didn't tell me anything, which just shows my ignorance, but at least I am curious so I did a search. And I found both a Wikipedia page and a webpage from Marx Toy Museum. And there are tons of Marx toys on ebay.
I wonder whether the flea market seller knew what she was selling. But I will from now one look more carefully at plastic toys. And next time I am in West Virginia I'll visit the museum.
