Starting in 1896, when he was only 15, we trace Picasso's artistic development, exploring his work as a youth, from the Blue period to the Pink period and his first steps into Cubism in 1906. Then we discover the Chrysteline period where he went from analytical to synthetic Cubism until entering his Neoclassical period in 1918. Part 1 culminates with the painting of his masterpiece "Guernica" in 1937.
