The logo, address, and phone number have changed slightly thru the years. You would probably end up getting two new ones. A couple of years ago, a detail person (actually an employee of that person--damaged the decal during buffing. The detail person had a local vinyl sign shop make an exact replica--of the one remaining. So any good vinyl sign company should be able to make you a replica of the remaining decal--or two if you wish.
Buying from C Dory would most likely be cheaper.
