By 1905, Picasso had largely overcome the depression that had previously debilitated him. Not only was he madly in love with a beautiful model, Fernande Olivier, he was newly prosperous thanks to the generous patronage of art dealer Ambroise Vollard. The artistic manifestation of Picasso's improved spirits was the introduction of warmer colors—including beiges, pinks and reds—in what is known as his "Rose Period" (1904-06). His most famous paintings from these years include "Family at Saltimbanques" (1905), "Gertrude Stein" (1905-06) and "Two Nudes" (1906).
