Francis Bacon portrait of lover George Dyer to go on sale

Artist chose study to appear in first big retrospective in 1971. Dyer was found dead in couple’s hotel room 36 hours before show’s opening

It is one of the most intimate and psychologically charged portraits that the artist Francis Bacon painted of his great love, George Dyer. So special was it to him that he personally selected it to appear at his first major retrospective at Paris’s Grand Palais in 1971.

But what should have been a monumental occasion celebrating Bacon’s stellar career was marred by tragedy when barely 36 hours before the opening, Dyer was found dead from an overdose of sleeping pills, exacerbated by alcohol abuse, in the couple’s shared hotel room.
