This is a very nice Last Supper piece. It is heavy 8 -10 lbs. my guess. It is a metal (copper, bronze, tin?) over ceramic or plaster. Whatever it is its heavy and appears to be held in from the back by

fasteners at the four corners, you can see this in the picture of the back. Im curious to see how its held in but I will not remove the paper and disturb the great condition of this piece.

Measures 7/8 x 12 1/2 x 18 1/2.
