An Italian artist has used his tractor to transform a field near the Italian city of Verona into a giant portrait of Russian President Vladimir Putin ahead of this week's Group of 20 summit.

The 135-meter (443-foot) -wide Putin portrait that Dario Gambarin created only can be properly viewed from above due to its scale.

Gambarin created similar land portraits of Donald Trump and Democratic candidate Hillary Clinton during the U.S. presidential race last year.
