Wieden+Kennedy creatives, Jason Scott and Joris Philippart, thought that there’s nothing sadder than abandoned Christmas trees; left out on the streets after the season’s festivities are finished. That’s why, in January 2014, they collected them to make this year’s Christmas cards.

The agency is turning their office into a shop selling the cards. There’s also a limited amount available at wklondon.com/ChristmasCards. All proceeds go to TreesForCities.org.
