My wife has owned a William Hartnell signed card, with him dressed as Dr Who, for over 40 years. It has lain undisturbed for all this time and have only now realised that it has real value.
I am about to sell it to an interested fan here in the UK, wish I knew more about values. I would hate to find out that I had undersold.
Seems to be everyone's idea of the ultimate find. It is genuine!
