This interesting billboard is an ad of Isbank (bank in Turkey). From a distance, one can see a police car hiding behind a billboard. This makes the drivers to slow down & read the small text on the board. Later, one realizes that the police car is rather a part of the billboard. Brilliant.
A really creative & beautiful idea used to promote the product; use of stickers on the road makes the vehicles to slow down.
Similar to the bank billboard ad. Though no information is known about this one.
Here is another cool one.
