This is a very rare item, a genuine TARDIS door sign, used during the filming of Series 5 of Doctor Who, the first to feature Matt Smith as the Doctor. The sign, having been used for filming was damaged en route to a filming location and was then replaced. The damage is apparent. One corner has broken off altogether (although is present and has been reattached by plastic film applied to the rear of the sign). Some of the letters have also come adrift and are missing. The photographs show the worst of the damage.
The discarded sign was rescued by Tristan Peatfield, who worked as Stand-by Art Director and then Production Designer on that series (between the departure of Ed Thomas and the arrival of Michael Pickwoad). I am selling it on Tristan's behalf, in aid of the charity that he and his partner Kim established in the name of their daughter Isabella, who was the youngest British victim of the 2004 Indian Ocean Tsunami disaster. The Isabella Peatfield fund raises money to support children's projects in Sri Lanka, where Isabella died. http://www.isabellapeatfield.com/
