The copy had lain untouched for more than 50 years in the library of the late Douglas, Lord Jay, economist, Labour politician, and president of the Board of Trade under Harold Wilson.

The book will be on view to the public from September 26 for one week at Peter Harrington, 100 Fulham Road, and offers are invited in excess of £350,000.

The current auction record for a first edition Frankenstein  with original boards is £95,000 (plus premium) achieved at Sotheby's London in October 2010.
