Abstract
A golf club putter having an alignment pattern is disclosed herein. The alignment pattern has first and second long lines that approach each other as they extend from an aft region of the putter to a front region of the putter and, when the putter is properly aligned with a golf ball, create an optical illusion of convergence of said lines at or near a center of the golf ball without actually intersecting.

An alignment pattern for a top surface of a golf club head comprising:
- a first long line;
- and
- a second long line,
- wherein the first and second long lines extend from a rear portion of the top surface of the golf club head to a location proximate a face of the golf club head,
- wherein the first and second long lines converge without intersecting as they approach the face,
- wherein the first and second long lines create an optical illusion of continuity past the face and into a golf ball when the golf ball is properly aligned with the golf club head substantially adjacent to the face,
- wherein the first and second long lines appear to intersect at a center of the golf ball when the golf ball is properly aligned with the golf club head substantially adjacent to the face,
- wherein at least a portion of the top surface of the golf club head comprises a dark color,
- wherein each of the first and second long lines comprises a light color that contrasts with the dark color,
