50 Times Thought-Provoking Advertisements Made People Do a Double Take

Billboards are as second nature as breathing these days. Most of us don’t consciously register how many we see in a day. With this ad, the company An Post decided to think outside of the box, or should we say outside of the billboard. They created a 3D advertisement to promote Christmas cards. 

The billboard was too high for anyone to touch it, but it created a cool visual. A giant heart was formed out of various holiday cards and postcards. Because of its interesting composition, it really made people stop and stare. This ad probably motivated more than a few people to send Christmas cards that year.
