As earlier reported by Outpost, the script has been signed by Tennant, Billie Piper and Russell T Davies.
It was given by Tennant to Arabella Weir, who played the Doctor in the Big Finish audio Exile, and will be sold by her in aid of a parent-teacher association of a primary school supported by Tennant, who is godfather to her son.
The fine art and collectables auction will take place at the auction rooms in Midhurst Road, Fernhurst, Haslemere, Surrey and will be filmed for the ITV show Dickinson's Real Deal.
There is a reserve price of 1,000 pounds on this item, although the auctioneers expect it to go for between 3,000 and 5,000 pounds.
No ticket is necessary to go along to the event.
The full details of the lot going under the hammer are given below, and are as stated by the auctioneers.
