Usually once a sign is out of print or out of production I can no longer find them. The rare exception is when I buy out someone who is going out of business and they happen to have “out of print” signs in stock. But for the most part, once they are sold out, I can no longer procure more. This is not a trick to get you to buy these signs right away, but a choice if you are considering several signs, which ones you might want to buy now rather than wait for your next order.
