Most Cash Registers came standered with an Amount Purchased top sign. National, Hallwood, American and others had the option of purchasing a personalized top sign for your register that would have said the owners name, business name, or a generic saying like "Call Again" or "Get A Receipt". In addition to this, you had the option of special ordering a personalized breast plate or back plate. Below are pictures of some of the personalized top signs, breast plates and back plates I have found over the years. Enjoy!!
