The technique used to make Juan Gris's glass and bottle of Banyuls is papier colle (or pasted paper), a technique sometimes wrongly referred to as collage. In this work, he has also used pencil and gouache painting on canvas. Juan Gris was a Spanish painter and sculptor, one of the most prominent figures of the genre of Cubism.
The technique of pasted paper was invented in 1912 by Braque and Pablo Picasso and it revolutionized the Western painting. They pasted pieces of newspaper, wallpaper or wood-grained paper onto their paintings and through that they managed to introduce real materials and different textures to their art.
