Experimental installations made from recycled plastic taken from street advertising by contemporary artist David Mesguich. From his background as a graffiti artist, Mesguich wanted to confront his past practice by questioning the concept of control of beings and spaces, visual pollution from advertising, contradictions from migration, people who are on the fence, and the passage from the concrete to mental world. These ephemeral sculptures are meant to degrade over time due to weather and other factors. His latest sculpture entitled Pressure 1.2 was installed on a train yard in Nantes.
