local iconography with modern treatments. This delicate manipulation of antique and contemporary references integrated to the use of graffiti writing, as well as the different manipulations applied on the wall: embossed, painted and carved, is his recognizable signature. It has inspired an entire generation of street artist. His influence grew worldwide after being the youngest artist exhibited in a major show at the Tate Modern museum in London in 2008. Nunca was described as "one of the rising stars of the São Paulo graffiti scene" in the 2005 book Graffiti Brazil which devoted an entire chapter to his work. He has worked closely with other major figures on the São Paulo graffiti scene including Os Gêmeos (the artist twins Otavio and Gustavo Pandolfo) and Otavio Pandolfo's wife, Nina. Cultural impact Having developed their reputation in São Paulo Nunca and the Pandolfos were invited to participate in a street-art exhibition at the Tate Modern Gallery in London that led to a significant re-evaluation of their work by their home city.

A 680-meter mural painted by the Pandolfos, Nunca and Otavio Pandolfo's wife Nina on retaining walls along the 23 de Maio expressway was half-obliterated with gray paint despite having been officially approved. Recognition abroad of the significance of the artists' work stimulated a public discussion of what constituted art which led to the creation of a registry of street art to be preserved by the city of São Paulo. Exhibitions Nunca has exhibited in Brazil at the Museum of Modern Art in São Paulo and around the world, notably in Greece at the AfroBrasil Museum and in the UK at Tate Modern, the first major display of street art at a public museum in London. The brickwork of the Tate Modern's external walls was decorated with paintings 15 metres high by the artists featured in the exhibition, the Pandolfo twins and Nunca, Blu from Bologna, the Parisian artist JR, the New York collaborative group Faile and Sixeart from Barcelona. Nunca’s most notable exhibitions also include Tag at the Grand Palais in Paris in 2009; The boneyard Project in Arizona in 2012 for which the artist painted the fuselage of a World
