I can't see close enough to the texture in the reds to work out if it could possibly be Boffo's execution of the Earthtones design. If it's him, there will be striations - very similar to old fashioned stained glass, within the reds and there will be streaky browns in it too.
But it is not in any sort of "grid" formation, which is what is most typical of his work.
There's something about the shape that makes me suspect something quite new.
I have encountered some new recycled glass from Africa, its made by Besmo, which is also incredibly similar to Earthtones, but the yellow in the glass comes from silver foil, and it's just streaky browns strapped over and marvered into it. I found it in the Natural History Museum in London, in the shop. (ethnic goods sort of thing).
It could also just be a studio piece.
