Artist carves a giant land portrait of Picasso to mark anniversary of his deathbr br To mark the 50th anniversary of the death of Pablo Picasso, Italian artist Dario Gambarin uses a tractor to carve a giant portrait of the Spanish painter in a field in the Italian town of Castagnaro. The portrait stretches over a 25,000-square-meter area of wasteland, making it the largest portrait of Picasso in the world, according to Gambarin. Gambarin says he created the work of art freehand, using a tractor, plow and rotary harrow.
