This is a Guardian 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 12,300 icons, all in the same style and quality.
This logo is shaped like two people walking next to each other. The bigger person is on the left side and has their arm around the smaller person. It looks like it might be a parent with their child maybe.
