General Electric heavy plaque, 16.5 inches by 20 inches, made of solid cast brass. This piece is quite heavy, and about 1/4 inch thick! Beautifully aged and patinaed cast brass plaque. Has many specifications listed on the front for the giant steam turbine to which this sign was once affixed. There are some minor paint splatters on the sign here and there, presumably from painting surrounding equipment, and the black paint on the sign shows some fading however the sign still displays beautifully. This is one killer piece of heavy industrial history! Please feel free to reach out with any questions, or view our complete catalog of items available for sale at IndependentAntiques.com
