Using this ingenious circa 1920s Golf-O-Graph golf ball marker, golfers could pick and set the letters to be marked on the ball and then mark away. This device is about as complete as you can get! All the small letters, the ink bottle, and even the tweezers used to handle the letters are included in the wooden pull-out box that fits inside the device.  It measures 5 ¼ inches in height and width. The golf ball shown in the device is for demonstration purposes and is not included in this lot.
