This is a Timezone -7 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.
A timezone -7 icon is a foldout map symbol and both sides of the map the lines will be straight. However, on the top and the bottom will be a zig zag pattern to show the foldout. An important aspect of the timezone -7 icon is that there will be a -7 in a circle on the map.
