Unnumbered and without Top Trumps insert, the UK version of the Time Crash set signed by David Tennant & Peter Davison for charity, limited to only 2 known pieces worldwide. These two items are pre-production sets that were given to the BBC Doctor Who Art Department who arranged for them to be signed by both Doctors and made available to raise money for the Lynn North Memorial Fund via two seperate charity auctions on ebay. In November 2009, the first signed Time Crash set raised an incredible £540 making this the most expensive Character Doctor Who Action Figure set ever. The second set raised £450 at auction for the charity.
