Hi Paddy,
As promised, I will get a good picture of the Corvette blown up from one of my photos from either Petit or Sebring and get it signed by the Corvette drivers or team whilst at Sebring. I will then get it framed and donate it to the auction.
Some advice, get something together on paper about the auction and the charities and then speak nicely to the teams at Sebring. They are in my past experience very accomodating as i collected items for another auction that benefitted the British Marshalls club.
Johnny O Connell donated a pair of boots which were then signed by all the Corvette drivers, ( I bought these and they are sat on my TV !)
Max Papis - A signed visor and gloves
James Weaver - signed gloves and boots,
Andy Wallace - gloves and boots, and visor,
Aston Martin - Goodie bag with t shirt, signed cap and flag,
Cadillac - signed t shirts and posters,
Audi - flag signed by the winners at Sebring (First diesel win)
I also donated David Brabhams podium hat that i managed to catch after the podium celebrations. Got it signed and added to the other items.
That was just from asking nicely at Sebring so give it a try.
