Up for auction is an 1880's original antique Thomas Kane brass post office box door. This very hard to find post office door has makers name on the front that reads: "Thos. Kane + Co. Chicago" with the number 233, which has a little tear. This door had a new key made for it, otherwise all in very good condition. Measure: 5 1/8" x 3 1/4". Also please check my other auctions for more post office items..
