This photo was chosen by National Geographic as the best “Picture of 1987”. An image fired after a 23 hour heart surgery by Dr. Zbigniew Regla. On the left of the picture is Dr. Sleepy disciplines after this long, not easy intervention.

The boy in the picture was named Diego Franzão Torquato, who is playing the violin at the funeral of his favorite teacher, John Evandro da Silva, the man who gave him the opportunity to escape poverty. Diego suffered from leukemia and passed away a year after the shooting of this photograph while he was 12.
