A rare copy of a book by Lawrence of Arabia is to be sold at auction.
Only 120 copies of the Seven Pillars of Wisdom were published by TE Lawrence at his own expense.
The book, published in 1922, was the inspiration for the film Lawrence of Arabia.
It recounts Lawrence's experiences during the Arab Revolt in 1916 and is expected to fetch up to £15,000 when it is sold in Edinburgh.
The copy is one of several books from the library of Scottish writer Lady Naomi Mitchison which are being sold by Lyon & Turnbull auctioneers.
Lady Mitchison, the author of more than 80 novels and hailed as the doyenne of Scottish literature, died in 1999 at the age of 101.
Other volumes up for sale from the library at her home, Carradale House, on the Mull of Kintyre, include first editions by EM Forster, Aldous Huxley, Virginia Woolf and John Betjeman.
Peter Nelson, book specialist at Lyon & Turnbull, says: "Seven Pillars is definitely one of the highlights of our sale.
"Many of the books have letters or notes from the authors - for instance, there is a letter from EM Forster describing where they should meet before the Oxford and Cambridge Boat Race.
"While they may not be in tip-top condition, many people might like to own a letter from one of Britain's literary greats for a couple of hundred pounds."
