Idea of Joining Queue Icon
The icon is shaped like three identical silhouettes of humans the top of their heads to their shoulders. The first silhouette has a arrow above it pointing down. The other two are partially hidden behind the silhouette in front of them and the trail off to the right side.
This is a Joining Queue 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 13,900 icons, all in the same style and quality.
