This little guy representing my namesake, Toad of Toad Hall, is a hood ornament on an early Rolls Royce Silver Ghost, circa 1915. The owner doesn't wish too many details disclosed, but the mascot has sat proudly on the radiator cap for many years.
It is alleged that Diana, POW had this version of the little guy on the bonnet of her first car. The House of Windsor has no sense of humor and had it removed, when she became an item. Too bad.
I have considered it for Camilla, but it somehow seems out of place. She can be yours though through Louis LeJeune for about $450 US.
