The Saatchi Gallery
Many artists showing at The Saatchi Gallery are unknown when first exhibited, not only to the general public but also to the commercial art world. Many of these artists are subsequently offered shows by galleries and museums internationally. In this effect, the gallery also operates as a springboard for young artists to launch their careers.
