OFFICIALLY LICENSED National Lampoon's Christmas Vacation Beanie! The National Lampoon's Vacations films that follow the hilarious Griswald family have always been fun comedies. The Christmas Vacation was no different. Each of these beanies features a fantastic allover Fair Isle design of things from the holiday film, like the Moose glass mug and the Griswold's station wagon carrying the infamous Christmas tree. The beanies are 100% acrylic.
