JR has the largest art gallery in the world. Thanks to his photographic collage technique, he exhibits his work free of charge on the walls of the whole world – attracting the attention of those who do not usually go to museums.

Originator of the 28 Millimeters Project which he started in and around Clichy-Montfermeil in 2004, continued in the Middle East with Face 2 Face (2007), in Brazil and Kenya for Women Are Heroes (2008-2011), the documentary for which was presented at the Cannes Film Festival in 2010 (Critics' Week).

JR has created "Infiltrating art". During his collage activities, the local communities take part in the act of artistic creation, with no stage separating actors from spectators. The anonymity of JR and the absence of any explanation accompanying his huge portraits leave him with a free space in which issues and actors, performers and passers-by meet, forming the essence of his work.

In 2011 he received the Ted Prize, giving him the opportunity to make a vow to change the world. He created Inside Out, an international participatory art project that allows people from around the world to receive a print of their portrait and then billboard it as support for an idea, a project, an action and share that experience.

In 2014, working with the New York City Ballet, he used the language of dance to tell his version of the riots in the Clichy-Montfermeil district. He created The Groves, a ballet and short film, the music for which was composed by Woodkid, Hans Zimmer and Pharrell Williams, and which was presented at the Tribeca Film Festival.

At the same time, JR worked in the abandoned hospital of Ellis Island, an important place in the history of immigration – and made the short film ELLIS, with Robert De Niro.

In 2016, JR was invited by the Louvre, whose pyramid he made disappear the with the help of an astonishing anamorphosis. The same year, during the Olympic Games in Rio, he created gigantic new sculptural installations throughout the city, to underline the beauty of the sporting gesture.

Portuguese artist Alexandre Farto (b. 1987) has been interacting visually with the urban environment under the name of Vhils since his days as a prolific graffiti writer in the early-to-mid 2000s.

His groundbreaking bas-relief carving technique – which forms the basis of the Scratching the Surface project and was first presented to the public at the VSP group exhibition in Lisbon in 2007 and at the Cans Festival in London the following year –, has been hailed as one of the most compelling approaches to art created in the streets in the last decade.
