Rare original 1960s Square Blue Glass Ceiling Light Shade, very tough to find in blue,  measures 11 3/4 in x 11 3/4 in, the is a very minor crack in one corner but is fully intact and nothing is missing, no issues. See pictures. The close up pictures, after the first 2 pictures, appear lighter in color due to our led lightning, the first 2 are true representations of the color you see in the room.
