First of all it will not be cheap. Anybody that has a real one will know its valuable.Somebody like Mike Kasmar who is a member here might have one for sale or steer you in the right direction.
Thanks for the referral Ian. I loooooves me some Stones items and as everyone agreed, the image posted is NOT one signed by Mick Jagger or any other Stones member. If you're Stones fans check out the wifeys website www.ilovemickjagger.com
