Looks like another bit has dropped off a Tetrap!
There were just three of these tetrap costumes made for the 1987 story Time And The Rani.
As with many costumes of the day, they have deteriorated. This is from one of these original screen used costumes sold in the famous bonhams auction.
I have seen small pieces of tetrap skin sell for £50-100 over the years on ebay but never such a large piece - this digit is in great condition and has been framed in a box frame.
It is supplied with a copy of the letter of authenticity and is s once in a lifetime auction!
It's been donated to us by Mike Tucker, the BAFTA award winning special effects designer, who's worked on Doctor Who since the 1980s. We're extremely grateful to Mr Tucker for his most generous gift.
