Abstract
A putter head comprising a novel alignment structure is disclosed herein. In particular, the putter comprises an alignment sphere attached to an upper surface of a lower flange and an alignment ring suspended over the lower flange and vertically aligned with the alignment sphere. When a golfer has oriented the putter properly in front of a golf ball at address, the alignment sphere will appear to the golfer to be encircled by the alignment ring.
