These are really cool stained glass mission style light/lamp shades. They are square in shape with graduated leading/glass toward the top and bottom. They're in great shape with the exception of this: One of them has a small crack (see photo) that hasn't broken through yet. The same one has some separation of the leading (see photo) which causes a little lift when picked up; it would need to be re-leaded or expoxied or something to make it secure.
They measure 8 wide by about 7 1/2 inches tall. The item "2 Vintage Tiffany Mission Style Stained Glass Lamp Shades Square Shape" is in sale since Wednesday, September 19, 2018.
