Kate Upton’s first ‘Sports Illustrated’ swimsuit file (AKA before a star was born)

Kate Upton’s first Sports Illustrated Swimsuit Issue photo file shows a fresh faced (and as usual, busty) young model about to hit it big. M.J. Day, queen of the SI Swimsuit issue (aka the person who holds our dream job), posted this picture to Instagram of an 18 year-old Kate Upton attached to what we presume to be the first Swimsuit Issue file for the soon-to-be crowned 2011 Sports Illustrated Swimsuit Rookie of the Year.
