It's an image of a baseball and bat. The bat is a tube with one end being thicker than the other, gradually becoming thinner from halfway down. On the bottom of the thin end is a oval representing a handle. Next to the bat is a circular ball with lines through it.
This Baseball 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 16,000 icons, all in the same style and quality.
