It's a drawing of a spade. The image looks like a spade that you would find on a playing card. The body of the spade is perhaps more prominent than the stem of the spade compared to a conventional spade drawing.
This Spades icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,700 icons, all in the same style and quality.
