At least a dozen years ago, I got a beauty, very similar to yours at Kirkland's. They switch their merchandise around so much that I have never seen one since and the irony of it is, that my housekeeper broke it before we ever got it hung. She was a great human being and I could not fault her. I had it in a bad place and she backed the vacuum cleaner into it pretty hard. Yikes! What a noise. I intended (immediately) go run out and buy another, but I just put it off too long and when I went, they no longer had them. I saw one similar in Penney's ads under mirrors long after I had decided on something else for that area. Try Lighting on the Net, Bellacor, Lamps Plus, the Mirror Lady, Kaboodle and E-Bay although I can tell you, sometimes looking locally at your glass places and furniture shops is more beneficial than searching the Web. A furniture shop in our town has some beautiful mirrors. I have known the owner for many years and she told me once if I ever get ready to replace that venetian mirror that she could get me one cheaper than I could get it on E-Bay, so look around town.

Check a few sites: https://franceandson.com/, https://www.1stdibs.com/, and https://www.allthedecor.com/decor/, One of the three will have it or probably be getting something very similar soon, france and son can have some issues with shipping, so just ask about it first before you buy, I bought some lamps there and they were fine but had to cancel a table because of an issue with shipping meaning they wouldn't ship large items, but maybe that's changed by now, allthedecor is going to carry similar items and should either have them now or soon...best of luck!

It's possible that it's paper, my paperhanger will laminate paper onto vents and other utilities. Look at Phillip Jeffries. They have nothing quite like this but they do have some very large scale specialty papers and metallics.
