Need help with Ron Lee clown

A friend recently gave me a Ron Lee clown signed "Ron (c) 80". It is simply Emmett Kelly Jr. standing with hands in pockets. I have tried searching the Ron Lee website, Google, eBay, etc., etc., etc., and cannot find this particular clown anywhere. I even contacted the Ron Lee home office, but they just suggested I buy their $31+ book. Does anyone have any information on this clown they can share with me? Thanks much for your help.
