This is a Address Book Filled 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 13,000 icons, all in the same style and quality.
This is a simple icon meant to represent an address book. It's a rectangle stood on end with rounded corners and the @ sign in the middle. The right hand side of the book is hatched with short lines to represent the rings that hold the pages inside the binder.
