Prince Harry shares his 2015 Christmas card

Prince William and Duchess Kate aren't the only British royals celebrating the holiday season with a sweet Christmas message.

William's younger brother, Prince Harry, is following suit. On Tuesday, Kensington Palace unveiled Harry's holiday card.

The card features a black-and-white photo of Harry with 95-year-old Tom Neil, the last surviving Royal Air Force pilot from the Battle of Britain.

"Merry Christmas from Prince Harry!" Kensington Palace tweeted. "Here's his Christmas card showing one of his favorite moments from 2015."

The moment stemmed from September when Harry and the veteran took part in an event to commemorate the Battle of Britain's 75th anniversary.

Over the weekend, William and Kate unveiled their holiday card. See it here.
