This guerilla idea is so out there - it's incredible. A giant soccer ball/car gets chased down the streets of Mexico by two enormous shoes (size 540). This is the kind of advertising that goes by and you just stop and stare - dumbfounded. That's what you call good advertising. Wish I could have been there for it. Brilliant (and hilarious) work done by JWT Mexico.
Thanks to Coliribus for the find.
