    Abstract: The present invention provides an approved golf club alignment system. The invention includes a putter head. The putter head includes a flat club face, a top surface and a bottom surface. The top surface has a cylindrical recess therein with a side wall and a circular bottom. Preferably, the side wall and bottom are in contrasting colors. The top of the cylindrical recess includes a lip with an inside diameter which is smaller than the inside diameter of the inside cylindrical wall. Therefore, when the golfer's head is properly over the putter head and the putter is level with the ground in all directions, the lip of the recess obscures the side wall of the cylinder. The golfer sees only the bottom circular surface. Because the side wall of the cylinder and the bottom surface are made of contrasting colors, if the golfer's head and club are not aligned properly, the contrasting side wall will be visible.
