The icon is the hairless face of a cartoon man. His eyes are open wide and he has a frown on his face. However, what seems to be popping out is his goatee, a small patch of hair on his chin.
This page contains the Goatee vector icon, as well as variations of this icon in different visual styles, and related icons. All icons are in the flat vector style, however, differ by the line thickness, fill, and corner radius.
