Can one still obtain a copy of the original sales sticker for my 61 Lincoln Convertible? from Ford ? or is there a private company that might have them archived?

Last time I read a request like this, the result was that dealerships can't reproduce them, nor can Ford, but a third party vendor could. Something about the placard being legal proof of ownership like a title or deed.
