Hello, I am new to this site. I have collected autographs on and off for about 35 years and mainly collect the odd one now to frame. I acquired this signed photo of Madonna about 20 years ago from a dealer. It has 13/28 on the back of it. I've seen similar style of her signature albeit an early signature of her but never confident that mine is genuine. Consequently it's never been on display. Any thoughts would be appreciated. Thanks John
