They are usually glued on. Try taking some fishing line and used it to pass behind the tag "By the Dean". You may have to work it back and forth several times to get it to remove the glue. It may take a while, but it can remove the tag. It removes the tag, and leaves no damage to the paint. You will want to go slow, and don't, and I say don't pull on the tag.
You can always take it to the dealer, and ask them to remove it, as it was not what you agreed to, but check the contract, some places the dealer will reserve the right to put something like that on your new car.
