This National Lampoon's Christmas Vacation t-shirt features one of the jars of jelly that Clark W. Griswold received for his Jelly Of The Month membership. Membership to this exclusive club was Clark's reward for a hard year's work of producing food additives. Although Clark was upset when he realized the club was in place of his bonus, Cousin Eddie correctly pointed out "that's the gift that keeps on givin the whole year". Everyone will immediately know that you are a fan of the 1989 holiday classic starring Chevy Chase when you wear this Jelly Of The Month Club Member Christmas Vacation T-Shirt!
