It's a logo of Poster reduced to a sheet of paper. The sheet of paper is slightly bent on the bottom right hand side and has a hole on the top. It looks like a normal poster you would see on a bulletin board.
This Poster 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.
