A golf putter head includes a body having a ball-striking face and an upper surface defined thereupon. First and second indicia are defined upon the upper surface. The indicia lie in a line which is generally perpendicular to the striking face. The first indicium is closer to the striking face than is the second indicium, and the indicia are spaced from one another and from the striking face so that when a golf ball bearing an indicium having a size generally similar to the size of the first indicium is disposed at a preselected distance from the striking face, and with its indicium uppermost, the first indicium will be equally spaced from the second indicium and from the indicium on the golf ball.
