Macy’s is back with “Another Miracle on 34th Street”. Their newest Christmas ad features Kris Kringle (aka Santa Claus) back at Macy’s to help new store manager Harold during the Christmas rush. Things have changed quite a bit since 1947 when Kris first came to Macy’s, but the star designers are there to show him the ropes. Watch Justin Bieber, Martha Stewart, Donald Trump, Carlos Santana, Marcus Samuelsson, Tommy Hilfiger and Taylor Swift to make appearances in the spot.
