Puma Social Cards

Everyone must have been exited about this one as it follow the trends of using Intagram on a night out and add a bit of fun and social on top of it. Sadly this is also the downfall of it: If you already use Instagram you are not going to switch to another app.

See above: a search for Any Time / Paris / Any teammate return 2 results.

Levis: #iamlevis

A really cheap campaign to produce but with with Instagram 13m+ users am sure they are onto a winner.
