nice cards mate, and the COA is a very nice touch. never thought to send them in to Select for a letter of auth. ive got the jezza sig so might send it in now ive seen yours. dont think you'll have too much trouble selling them mate.
btw the rumour is true then, bob pratt did sign common cards as signature cards for the series.
So did Trevor Barker. I have the Barker one and thought it was weird the time I pulled it that is just looked like a common card with a signature on it.
