(AAB-330/ABF-10-1) Footballers (Bazooka)
Peter Ricketts has provided scans of the backs of two Tony Knapp cards, one where the right leg is not shaded and the other where the leg is shaded. I am not aware of any similar variations though I did find a Frank McLintock card with his left arm unshaded - the search is on to find one where the arm IS shaded.
