While other street artists take to vertical walls, for Ella and Pitr, the ground is their canvas.
Ella & Pitr met in 2007 and decided to combine their talents.
Later they started painting on rooftops, airplane runways, and even huge grassy fields.
Their latest mural is reportedly the largest outdoor mural in the world to date at 226,040 square feet.
Titled Lilith and Olaf, the piece illustrates a curled-up woman with a small figure dropping from her fingers.
The figure is King Olaf I of Norway, who ruled the country from 995-1000.
