Josef Rataj is known as a pioneer of the Pop-art artistic movement in Bohemia, and also as a Speed Painter. He is a favourite of Czech celebrities, whose portraits he portrays in his own distinctive way, which is inspired by the style of Andy Warhol. His family built a positive relationship to art in him from his early childhood. He and his grandmother regularly visited the "Masné krámy" gallery in Pilsen, where his grandfather, the academic painter Josef Jícha, exhibited. Today he is a sought-after pop-art painter and artist.

Josef Rataj (* 29 May 1979, Plzeň) Painter, artist, performer. He came to his own work during his repeated trips to Los Angeles, where he was completely captivated by the advertising design and kitsch style of 1950s pop art, the glittering Venice Beach and the vibrant advertising signs of Las Vegas casinos. The overwhelming appeal of neon colours, invincible superheroes and a world of growing consumerism steered him towards his current artistic career. Today, Josef Rataj ranks among the most sought-after pioneers of this style in our country. Josef likes to support charity events and that is why we appreciate his participation in the Czech Ball.
