This cover image released by Doubleday Books for Young Readers shows, "The Purloining of Prince Oleomargarine," by Mark Twain and Philip Stead, with illustrations by Erin Stead. The unfinished fairy tale that Mark Twain told his young daughters in the 1870s is being published. The contract for the story's sale to Random House was steered through Hartford's Mark Twain House and Museum as a way to shore up the finances of the building where the author raised his family.
