Spanish Brass/Bronze (?) Relief Last Supper Art

[KirbyDog]

We have this art piece, been in the family for decades. When the grandparents moved out of their house, we realized we knew little about this piece. Compared to pics we've found online of similar pieces, this one is unique in several ways including the lamps in the ceiling and the depth of the relief figures. Very detailed. Wood frame seems to be original to the piece. We did not want to take the paper backing off the piece to look for artist name because we didn't want to damage anything.

Wondering if anyone has an idea of its origin or in particular, it's value. See pics. Would love any feedback!!

Thanks for the response vpnavy, I have been busy or would have responded sooner. When we checked ebay ourselves we didnt see this listing. Perhaps because it was from the UK. Interestingly the basic design is very similar, but ours is much larger and more detailed. And ours seems to be decades older as well, assuming the ebay listing is newly pressed. At least we can be certain that it is of Spainish origin now. We tried a few antique sellers in our area, but they seemed more interested in the frame, as there are few true experts in religious art here. We won't give up just yet. Thanks ahead of time for any more advice your community has!
