A rare piece of Doctor Who history is now up for auction.

William Hartnell’s (aka The First Doctor) personal script for the first ever episode of the iconic show is up for bids, estimated at between £5,000 and £8,000, according to Antiques Trade Gazette.

Doctor Who and the Tribe of Gum (the working title for the show’s first episode) was written by Anthony Coburn, and was previously featured on Antiques Roadshow.

Interestingly, Hartnell’s 1963 script features the blue markings of annotations, and was discovered by the grandfather of the vendor while refurbishing the late actor’s flat.

The script is up for auction through Aston’s Auctioneers of Dudley in the West Midlands on May 3, and it is not the only one going either.

A Welsh auction house is offering original scripts for unaired Tom Baker-era serial Shada, written by Douglas Adams, and they are going for between £200 and £400.

Hartnell’s First Doctor recently featured in the Doctor Who Christmas special, played uncannily by David Bradley as we said goodbye to Peter Capaldi’s incarnation of the Time Lord and hello to Jodie Whittaker’s Thirteenth Doctor.

As well as finally putting a female Doctor in the TARDIS, it looks like the new series of the show will have much more female writing talent too.

BBC drama head Piers Wenger confirmed this week that several episodes of series 11 will be penned by female writers, explaining: “Having a diverse team on that show feels appropriate, important and essential.”

Doctor Who will return later this year on BBC One.
