Nude, Green Leaves and Bust is a portrait of Marie-Thérèse Walter from 1932. She was a mistress of Pablo's, and appeared many times in his work. His art and personal life would often intertwine like this, as it did for so many expressive artists.

Whilst truly abstract, Picasso also uses light effects in this work, as well as twisting his model into a surreal form. Over time he would alter her appearance further and further, until artworks would be truly surreal and abstract.

This particular Picasso artwork rose to prominence in 2010 when it was sold at Christie's in New York for $106.5 million. At the time, this was a world record and marked the start of a frenzy of activity in the art world as other investors looked to move funds into the art market.

Picasso chose nudes for many of his portrait paintings, and these serve as an interesting genre within his overall career.
