vintage square Holophane prismatic glass pendant shade

Deco, 1930s vintage, square bottom prismatic glass pendant shade. This vintage shade is marked "Holophane" and "3774" on the bottom edge of the shade. This square Holophane shade measures about 11 1/2" square across the bottom of the shade, 6 3/4" high and 4" across the fitter rim. This shade has a few chips to the rim of the fitter, but they'll never show when the shade is in place.
