Star Cards

Last Saturday I was up in York, visiting family. While up there we took a trip to the Castle Museum. There wasn't an awful lot there related to astronomy (there was a display case full of instruments made by T. Cooke & Sons — which included a really nice brass achromatic telescope) but, in the display of children's toys, I did find these rather nice "Star Cards":

Sadly I couldn't see any information about them. I'd love to know who made them and what the story was (and how many there were in a set).

They reminded me of the time when, as a child, I made my own set of constellation cards.
