 The Rockwell painting shows a man perched atop a ladder and adjusting one of the Marshall Field's clock to correspond with his own pocket watch.The old Oriental Theatre in the background proves this depicts the matching "Great Clock" at the northwest corner of the building at State & Randolph Streets.In 1948, Rockwell donated the original painting, ""The Clock Mender"", to the store, where it had hung on the seventh floor ever since.
