If you happen to be in to marketing like I am, then you will enjoy this website. It is called Ads of the World and the name is pretty self-explanatory. The website has collected pretty much every single ad campaign from all over the world for you to look at.
On the website you can search for ads by type of media (print, outdoor, TV etc.), or by region, country, or industry.
This is an ad I found in the Outdoor section under Type of Media.
It is an ad for the Zoo in Copenhagen, Denmark. I really like this ad because it is very creative and it is executed perfectly. It really looks like a huge snake is squeezing that bus into pieces.
