Carolingian Style Plaque

The plaque measures 20cm x 12cm and weighs c.800g
It seems to be made of stone or some kind of composite.
It looks like a replica of an ivory plaque in the V&A which is catalogued as Carolingian.

I would be grateful for an information and light that anyone can shed

Oh. I've just twigged that this is the 20th Century forum. I guess this could be a 20th C copy but maybe not.

We cover all eras these days. There was a fad for making copies of ivory religious plaques in the 19thC but they tended to be made from an alabaster-like plaster-of-paris and this looks like cement. In Ireland they use pressed peat.
I think this may be a 20thC copy

It feels like cement so that makes sense. It is an exact copy of one in the V&A . How would someone get permission to do that? I’m trying to research but stumped. Thank you for your help

There were moulds taken from the originals in Museums in the 19thC, and the copies were sold on subscription - I assume as a way for the Museums to raise funds. They also made copies at the Art Academies for the students to draw. I expect those original moulds were still available for commercial use into the 20thC
