This is one of the very first ‘real’ large paintings by Picasso. It was created in 1897, when he was only 16 years old (he started it while 15). The painting is the culmination of of some sort of the earliest period of Picasso, before he went to study in Madrid. His father appears in this painting as the doctor.
