This invention relates to a marking system for a golf iron which provides a visual marking system to facilitate the positioning of the ball laterally with respect to the club face, as well a marking system on the bottom flange of the club which facilitates the determination of lie angle, and a bullseye marking at the sweet spot of the club face. The markings make it possible to facilitate club fitting.
