Paintings by Pablo Picasso are being exhibited around the world. Picasso's work is considered to be one of the most important pieces of art in the history of the world, according to a study by the University of California, Los Angeles.

The study found that the work of Picasso and other painters such as Salvador Dali, Frida Ghitis, and Pablo Casals was more important than the art itself. The work of Dali and Casals has been called "the most important work of all time"
