Not magic lantern slide !

I think this series of cards were to use with a projector called an epidiascope . When I started teaching we had a ‘ modern ‘ one .
It was very useful to project pages of books onto a screen!
This card is from ‘ stories for children ‘ and would be taken from a magic lantern slide .
Hope this makes sense …..sk is blipping some old interesting magic lantern slides and I thought I would join in:-))
