Nope. It was on one of the art threads, just a post in passing. Art threads, zillions of them here, but it wasn't one of those about identifying or valuation of a work, or at least I'm guessing not - more one of those Tsar or I or someone else would start about art trends (and such).
I'll mosey over to look around and see if I can find it, one of these days when I can't stand another politics thread. The toilet lid painting wasn't even all that interesting as such, not to knock it either, just that I thought it was an amusing thing to do.
