A Francis Bacon painting on loan from an Iranian museum goes on show in London on Friday for the first time in more than 30 years.
Two Figures Lying on a Bed with Attendants was painted by the renowned British artist in 1968.
The three-panelled work was acquired by Tehran's Museum of Contemporary Art in the 1970s.
It will be on display at the Tate Britain gallery in London for six months. Bacon died aged 82 in 1992.
Another triptych painting by Bacon is to be auctioned at Christie's in London on 24 June.
The auction house estimates the 1966 work, titled Three Studies of Isabel Rawsthorne, will fetch between £1.5m and £2m.
The sitter, Ms Rawsthorne, is believed to have been Bacon's only female lover.
The painting is part of Christie's Post-War and Contemporary Art sale.
Bacon was born in Dublin but moved to London at the age of 16 before spending time in Paris and Berlin.
He became involved in the surrealist movement that became popular in post World War I Germany and France.
One of his first major influences was Picasso.
He had his first big solo show in London in 1934 but did not begin to paint intensively again until 1944.
Bacon went on to have his work shown in the US, France, Italy, Holland and Switzerland.
Some found his paintings unsettling and it was not until 1962 that Bacon's reputation was finally assured with a major exhibition of his paintings at the Tate gallery.
