The mark consists of a uniquely shaped three-dimensional configuration for the peg head portion of a guitar or base as illustrated in the drawing by solid lines. Specially, the mark includes a veneer overlay represented in the drawing by the innermost set of solid lines which is affixed to the larger head stock portion that has a semi-circular hole cut into it as represented in the drawing by the outermost solid lines. Both pieces together make up the complete mark. The dotted lines are not part of the mark.
