What's Up, Doc?

With apologies to Warner Brothers, I've invited Professor Wabbit to say a few words about Francis Bacon's Three Studies for a Self Portrait, which comes under the hammer at Christie’s Post-War and Contemporary Art Evening Sale in London on 30 June. Take it away, Prof.
"What's up, doc?"
Thank you, Professor Wabbit.
Tasteless billionaires note: Lucian Freud's Naked Portrait with Reflection will also be up for grabs.
