The Gilded Man (comics) "The Gilded Man" is based on the centuries-old legend of El Dorado. The main characters in the story are Donald Duck, his nephews Huey, Dewey and Louie, and his cousin Gladstone Gander. Minor characters include Philo T. Ellic, The Old River Man, and The Gilded Man. Barks created the fictional U.S. state of Calisota as the location of Duckburg in this story. The story obviously references the world’s most valuable stamp, the legendary 1856 British Guiana 1c magenta which in 2014 was auctioned for $9,480,000. The stamp is presently on display at the National Postal Museum of the Smithsonian Institution
