Sir Geoff Hurst signed photo

I now have in my hands a signed photo from Sir Geoff Hurst. It is a signed photo of him scoring his third goal in the 1966 world cup final.
Sir Geoff Hurst made his mark in World Cup history as the only player to have scored a hat-trick in a World Cup final. His three goals came in the 1966 final for England in their 4–2 win over West Germany at the old Wembley. Such an achievement was made all the more remarkable by the fact that he was only five months and eight games into his international career, and was not considered his country's premier centre forward.
He played most of his games in England for West Ham so if you have a relative who is mad about the hammers this would be an ideal xmas present.
This is being sold to raise money for the SPARKS charity who i am running the london marathon for.
I do have a figure in mind but will see if there are any offers.
Thanks in advance.
