a very good artikel on shadow puppetry.

Maybe you can help me in finding out something about 12 old (100 Jears ) chinese shadow
puppets made of some kind of very thin hide (leather). They are not as colloured as the ones in your artikel. They are mostely black with very intensive colloured parts if you hold them into the light. You dont see that they are colloured if just looking at them
The 12 different puppeys seem to have gotten some restauration effords. Each of the puppys is in a black picturefraim between two sheeds of glass (25 cm 10cm). Looking quite impressive I must say.

Maybee someone can help me finding some kind of history about them like how old, exakt origin, some museum I could find out moore about them
