Carlsberg, a Danish brewing company, set up a billboard that dispenses beer at London's Truman Brewery. Pedestrians were able to obtain a free beer by waiting in line by the sign.
The billboard boasted a slogan which read, "Probably the best poster in the world".
There have been plenty of creative billboards in the world, but none of them claim to be the best. At least this sign shows a little humility by including the word "probably".
Here are a few billboards that surpass the typical ad in terms of creativity.
What is the best billboard you have seen? Post in the comments if you have one.
