This MCM Vintage Industrial Size White Enamelware Ceiling Light Fixture Shade dates to the 1930’s and comes with the original green metal fixture at the top the light fixture fits into. It's 20” wide across the black painted rim, it’s approx. 14” tall overall or 9” to the top of the shade itself. It’s 7 3/4” across the bottom rim of the green metal fixture on top that attaches to the shade with 3 clamp style clips, and the hexagon opening at the very top is 1 1/2” wide or 4” at the bottom of the cone. There is some chipping of the black paint around the rim, but otherwise it's in very good vintage condition.
