This is a Group Message 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.
The icon is a picture of group message. The icon is the shape of two rectangles. The rectangle in front of the other one looks like an envelope. The envelope looking rectangle is slightly lower and to the right of the rectangle behind it.
