This was an estate purchase. I love the old, vintage post office memorabilia, merchandise. Selling as I purchased. With key. Hopefully the 7 photos will speak for the description. Heavy for size. A metal material, maybe embossed or brass ? designs. It's the hinged cover piece that goes on front of the post office box. It measures approximately 11 inches across. Approximately 6 1/2 inches top to bottom. The scale shows it weighing a little over 3 1/2 pounds. Different shipping options a...vailable. Thanks for your interest and looking.
