It's a depiction of a can of Spam. The can is made up of a rounded square with a lid on it. The lid has a tab on the right side and the main can has SPAM written on it in the center.
This is a Spam Can 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 13,300 icons, all in the same style and quality.
