What do you think an artist is? An imbecile who has only his eyes if he's a painter, or ears if he's a musician, or a lyre at every level of his heart if he's a poet, or even, if he's a boxer, just his muscles? On the contrary, he's at the same time a political being, constantly alive to heart-rending, burning, or happy events in the world.
Pablo PicassoIn one way or another, I always marked my pictures. But there were times when I put my signature on the back of the canvas. All my works from the cubist period, until about 1914, have my name and the date on the back side of the stretcher. I know someone spread the story that in Cรฉret, Braque and I decided not to sign our pictures anymore. But that's just a legend!
