The subject of an oil painting by former Walt Disney Co. artist Carl Barks may have been Donald Duck, but the price was hardly Mickey Mouse: $75,000. Pennsylvania real estate tycoon Robert E. Hall bought the Barks painting from Another Rainbow, a Disney licensee in Indianapolis. The painting, featuring Donald, Uncle Scrooge, and siblings Huey, Dewey and Louie, is named “Makings of a Fish Story” and was painted earlier this year. Barks, who lives in Oregon, wrote and drew more than 500 comic book stories about the duck family from the 1940s to the mid-1960s. At least eight of Barks’ oil paintings have sold for more than $70,000.
