The ads, which take the form of different animals made up of Londony urban landmarks and icons, apparently are "designed to articulate the importance of the urban audience and the fact that CBS Outdoor are best placed to engage with this valuable and hard to reach group of consumers". Not sure if it's just me but this kind of reminded me of Animals on the Underground - a whole collection of animals that could be "found" by looking in the Tube map!
Anyway look out for some familiar London icons in CBS's campaign. You'll see the O2, Millenium Wheel, Wembley Stadium, St Paul's Cathedral, Big Ben etc etc
The campaign's only in London at the moment but from January 23rd you'll see it being rolled out to Manchester, Birmingham, Glasgow, Bristol and Liverpool. So there will be icons featuring Old Trafford Centre for Manchester, The Beatles for Liverpool and the Bullring Bull for Birmingham. The others will have region specific landmarks.
If you visit www.facebook.com/cbsoutdooruk you can see all versions of the London posters. As a secondary element to the campaign they're offering people the chance to win city experiences throughout 2012 by liking them on Facebook & filling in a few extra details like age & region!
