Marshall Field meets Harry Potter along State Street in a topical twist to an 80-year-old tradition. The traditional three-story Christmas tree at the flagship department store will be adorned in a Harry Potter theme, with 1,000 hand-carved and painted ornaments including Harry Potter's Nimbus Two Thousand broomstick, a potion bottle, Hedwig the owl and the Mirror of Erised. Meanwhile, the tale of 'Harry Potter and the Sorcerer's Stone' unfolds in 11 windows, with scenes that include life with the Dursleys, Hagrid and the Diagon Alley and Harry's arrival at the Christmas feast.
