Yes, its history can only be verified by its own records. No poets, writers or famous persons from the past has ever made reference to them. They've claim some royalties have worn their scents, but no one can vouch. Creed came about around 1970 before then, their is no true history.
Unlike Guerlain, which can be verified through different books, writtings,etc. Many books have been written about or made reference to Guerlain. Writers such as Collette, Marcel Proust. Royalties such as the Empress Eugine even gave him the right to use the royal french emblem of the Bees.
Creed has no such warrants. Even the Coat of Arms that is make to look like the Prince of Wales code of arms minus it "Ich dien".
Creed's history is all self proclaimed, only reference they get is through their own packaging. Guerlain, Chanel, Panheligon, Floris, Lubin, Molinard, Coty, etc...those are names that history can back up.
