William Bouguereau’s La Jeunesse de Bacchus (The Youth of Bacchus) has been in the French painter’s Paris studio since 1884, and has previously left only three times for exhibition.

But exactly how do you ship a 20-foot, 135-year-old painting mounted within a 1,300 pound frame? And what makes this painting so special anyway? Watch.
