This is a Postcard 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 shaped like a horizontal rectangle with a dotted line at its center. At the top right corner is a small square shape. Under the square at the bottom center are three horizontal lines, one on top of each other.
