When reviewing Volume 76 of Doctor Who: The Complete History, I realised I didn’t have the Stuart Manning poster used by the Radio Times for that story. It is now attached to this article. It was used by the Radio Times for: Doctor Who: Exclusive Into the Dalek poster revealed.
As a very belated bonus, I popped by the umbridge DeviantArt page and dug out his equally excellent poster as well (right!). Enjoy!
