Often spending as long as two weeks on a piece, Argentinian street artist Eduardo Relero is the artist behind some of the most amazing large-scale optical illusions.
Now living in Madrid, Spain, Relero, 48, uses the pavement we walk on everyday as his canvas, making just another street into a magnificent work of art.
Relero says he began his street art in 1990 on the streets of Rome and has since left his mark on France, Germany, the United States, Mexico, and Spain.
“I realized that by taking my art out in the public, to festivals, theaters and events, I would be free to make drawings more to my liking.”
