It is an icon of a persons face with sideburns. There are two dots for the eyes and a line the curves downward for the mouth. The icon stops above the eyes and has two half circles on the outside to represent ears. There is a circle on each cheek shaped like a pipe or animal tusk that represents the sideburns.
This is a Sideburns icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,700 icons, all in the same style and quality.
