Keep your drink as cold as Clark Griswold, after an afternoon stuck in the attic, with this fun "National Lampoon's Christmas Vacation" acrylic travel cup. The red "Merry Clarkmas" cup features a photo of Clark smirking in his Santa hat, and the domed lid acts as a snow globe, with snowflake-shaped glitter and a stylized silicone moose mug inside. Double-walled cup with screw-on lid includes a tall straw and makes a fun gift for a secret Santa or teacher appreciation.
