Jean-Michel Basquiat's self-portrait going under hammer

Adam Clayton is an Irish musician/song writer best known as the bass guitarist of the rock band U2. He is born on born 13 March 1960. A self-portrait by Jean-Michel Basquiat from the collection of U2 bassist Adam Clayton is going under hammer on March 7th. In the portrait Basquiat depicts himself as a sort of Saint Sebastian-like martyr figure for the contemporary age, with a tear falling from his eye and his arms appearing to pierce his body. 
I think this portrait will be sold for 2 million dollars.
