Input (English): Jasper Johns's Racing Thoughts and Kaspar Malevich's Solar Eclipse with [this work] both feature recreations of it, the former in black and white and the latter with two red Xs. Fernand Leger created a version "with keys," while E. H. Gombrich pointed out the distinctive sfumato at the corners of the eyes. Margaret Livingstone claimed that this painting's most famous feature is captivating because it is not perceptible by foveal vision and thus nearly disappears when it is looked at directly. Featuring an added mustache in Duchamp's parody L. H. O. O. Q., for 10 points, name this painting famous for its subject's lack of eyebrows and enigmatic smile, a portrait by Leonardo da Vinci.
