Timezone -4 Icon in iPhone Style

This is a Timezone -4 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.
There is a rectangle with zig zag lines on the top and bottom in the shape of a half-folded out map. The rectangle has four columns of spared dots representing print and overlapping the one quarter of the rectangle in the bottom right corner is a circle with minus four inside of it.
