This year's theme for the historic window display at Macy's is "The Magic of Christmas," celebrating holiday traditions such as Macy's Thanksgiving Day Parade and "Yes, Virginia," the animated special depicting the story of 8-year-old Virginia O'Hanlan in 1897 asking a newspaper editor if there is a Santa Claus.
The windows also will feature Pittsburgh traditions and landmarks, including The Rink at PPG Place, the historic Kaufmann's clock, the My Macy's Holiday Parade and Light Up Night itself.
A few facts about the windows:
■ The display is a tradition that dates back more than 100 years.
