This was a vintage piece from the 1920's. I mounted it on a mahogany veneered background inside of a vintage round frame within which I built mahogany veneered sidewalls. This was a tough piece to do as it was obviously round! So I had to cut the glass by hand of course as well as the backing that I had to build out for depth and strength. Irregular pieces are always a challenge (and they don't get much more irregular than this!) and I generally enjoy doing them as they break up the monotony of the usual never ending "factory line" every day stuff, although a bit frustrating when you have to deal with time constraints!
