I think Just-B said it best regarding the difference between a logo and an illustration. I would only add that if unicorns do exist, I think they would be disappointed in the way most humans think of them as fuzzy, cuddly, cotton candy creatures. In his book, THE GREAT DIVORCE, author C.S.Lewis describes them as heavenly winged creatures whose primary function is to battle evil and who have healing power for their riders in their horns.
