Video shows the making of a large, hand-painted poster ad for the A7 near the former Checkpoint Charlie in Berlin.

This video from Audi TV shows the making of an ad for the new A7 going up in Berlin.

The footage shows the artists at work hand-painting the poster ad with spray paint on a very large white canvass before the Berlin crowds around the former Checkpoint Charlie.

It took the four artist 14 days and 200 cans of spray paint to make the ad.

The ad text translates as: "Nothing is as inspiring as a blank sheet of paper. It is the opportunity to create something original."

And the way this ad was made is the original piece of work. The A7 Sportback we've seen before.
