This metal advertising cabinet came from a relative's automotive shop years ago. He says it was distributed in the 1940s by Guide Headlamps to advertise their new sealed beam headlights. It's made of metal, about 51" tall and 22" wide at base, in the shape of a lighthouse. Top door opens to hold a headlight and back door opens to reveal two shelves, which he says held a battery to operate the display. It's in very good shape, a few minor dings and one scratch on front. It's been stored in our basement for years and we've never seen another like it. Was wondering if anyone could place a value on it?
