According to Christopher Finch, author of Norman Rockwell's America, "Marriage License", which appeared on the cover of the June 11, 1955 edition of the Saturday Evening Post, was one of a handful of Rockwell's works "...in which Rockwell managed to pull all of his skills and powers of observation together - in which he defied deadlines and produced something which transcends the category of good illustration." Finch numbered "Marriage License", "Saying Grace", "Girl at the Mirror", "Shuffelton's Barber Shop" and "Breaking Home Ties" as among Rockwell's finest works.
Inspired by a true story, Invincible recounts the last 48 hours in the life of Marc-Antoine Bernier, a 14-year-old boy on a desperate quest for freedom.
