Hot Wheels
The toy-cars brand introduced by Mattel in the sixties was a hot success. This wasn’t their only creative billboards, but the brand worked with different advertising agencies to come up with different 3D billboards and road signs in an attempt to market their product.
Their different campaigns usually 3D posters of giant kids looking at the cars passing by as if the cars were their Hot Wheels toys, and in that way, they actually make their audience an inseparable and almost active part of the commercial.
