The graffiti artist Rafael Sliks was born in São Paulo, Brazil. His study of calligraphy has influenced his art: his graffiti signature creates a new aesthetic that gives birth to new artworks in murals, on doors, or in images. His abstract works highlight different types of lines, taking people on a journey through his universe filled with calligraphy, colors, and textures. Writing is his art. Writing is his way of expressing, denouncing, communicating, and creating beauty. All of his graffiti can be seen on the streets of São Paulo, as well as in exhibitions in Miami, Berlin, Taiwan, and many other places.
