The one million pound bill is one of Mark Twain's funniest stories, which earned him a movie. An honest American lost and ruined in London attends abrupt changes in his fortune, at the hands of two eccentric millionaires. All his honesty and abilities are put to the test. Twain asks us here with his usual humor and irony questions such as the true value of money, the veneration and hypocrisy that arise around him, and the sense of honesty, friendship and love. Marcos Morán's illustrations enrich the story.
