A nice piece form DDB

[singlepic=15,320]
S potted this ad on Adsoftheworld. Liked the simplicity of it. A nice little storyteller. 
There’s been a lot of buzz in Sweden about DDB but personally I haven’t really understood why. But when I spotted this one it makes more sense.
Among others, Art Directors Viktor Arve, Ted Harry Mellström, Simon Higby and another 7 team members created this piece. Can someone please explain why you need 10 people to produce this one. Hope the client didn’t have to pay.
