Joan Miró i Ferrà (Barcelona, April 20, 1893-Palma de Mallorca, December 25, 1983) was a Spanish painter, sculptor, engraver and ceramics artist. In his works he reflected his interest in the subconscious, in the "childish" and in the culture and traditions of Catalonia. Although he is associated with abstract art for his mature style of stylized and imaginary forms, in his youth he began with figuration, with strong Fauvist, Cubist and Expressionist influences, moving on to flat painting with a certain naive air.
After his stay in Paris, his work becomes more fanciful and dreamlike, coinciding with the points of surrealism and joining this movement.

Andy Warhol (Pittsburgh, August 6, 1928-New York, February 22, 1987) was an American plastic artist who played a crucial role in the birth and development of Pop Art. Following a successful career as a professional illustrator, Warhol gained worldwide fame for his work in painting, avant-garde film, and literature, a notoriety that was backed by a skillful relationship with the media and his role as guru of modernity.
He used different media to create his works, such as hand drawing, painting, printmaking, photography, screen printing, sculpture, film, and music.
Fame and controversy aside, he is considered one of the most influential artists of the 20th century due to his revolutionary artwork.
