Keno Don Hugo Rosa, known as Don Rosa, is an American comic book writer and illustrator known for his Disney comics stories about Scrooge McDuck, Donald Duck, and other characters which Carl Barks created for Disney-licensed comic books, first published in America by Dell Comics. Many of his stories are built on characters and locations created by Barks; among these was his first Duck story, "The Son of the Sun" (1987), which was nominated for a Harvey Award in the "Best Story of the Year" category.

Scrooge McDuck is a cartoon character created in 1947 for The Walt Disney Company by Carl Barks. Appearing in Disney comics, Scrooge is a Scottish-born American anthropomorphic Pekin duck. Like his nephew, Donald Duck, he has a yellow-orange bill, legs, and feet. He typically wears a red or blue frock coat, top hat, pince-nez glasses, and spats varying in color. He is portrayed in animation as speaking with a Scottish accent. Originally intended to be used only once, Scrooge became one of the most popular characters in the Disney comics world, as well as Barks' signature work. Scrooge is an extremely rich duck who lives in the fictional city of Duckburg in the fictional U.S. state of Calisota, whose claimed location is in California in the real-world United States.
