The script for the very first episode of Doctor Who, as used by the first Doctor himself, William Hartnell, is being auctioned next month.
The script for An Unearthly Child is 43 pages long and contains blue pencil annotations made by William Hartnell as he was developing the character of The Doctor.
It was discovered by the vendor's grandfather whilst refurbishing the home lived in by Hartnell, and his wife Heather, during the time he was working on the series. The script featured in an episode of the Antiques Roadshow shown last Christmas.
The script is being sold by Aston's Auctioneers and Valuers at their Film & Music Memorabilia & Comics Auction on Thursday 3rd May. It is expected to raise between £5,000 and £7,000.
