Picasso's Blue Period (1901–1904), which consisted of somber, blue-tinted paintings was influenced by a trip through Spain. The Museu Picasso in Barcelona features many of Picasso's early works, created while he was living in Spain, as well as the extensive collection of Jaime Sabartés, Picasso's close friend from his Barcelona days who, for many years, was Picasso's personal secretary. There are many precise and detailed figure studies done in his youth under his father's tutelage, as well as rarely seen works from his old age that clearly demonstrate Picasso's firm grounding in classical techniques. Picasso presented the most durable homage to Velázquez in 1957 when he recreated "Las Meninas" in his characteristically cubist form. While Picasso was worried that if he copied Velázquez's painting, it would be seen only as a copy and not as any sort of unique representation, he proceeded to do so, and the enormous work—the largest he had produced since "Guernica" in 1937—earned a position of relevance in the Spanish canon of art. Málaga, Picasso's birthplace, houses two museums with significant collections, the Museo Picasso Málaga and Birthplace Museum.
