Leon Keer is one of the world's greatest artists of anamorphic street art, this astonishing style that creates an optical illusion or a trompe l'oeil. These unique works, often produced in three dimensions, are inspired by contemporary themes or environmental concerns and ask questions about our quality of life. In addition to the optical illusion, the Dutch artist also likes to combine new technologies such as augmented reality or video mapping. For him: “Each piece of street art is unique. It belongs to the street and to its inhabitants. Its ephemeral side reinforces its existence. Internationally known, Leon Keer's works roam the streets of Europe, the United States, Russia, Mexico, the United Arab Emirates, Australia and several Asian countries.
