This is a 3D rendering of a Canadian flag "plastered" with OS/2 all over it. The file is in .PNG format, and when converted to a .BMP format (using PMView or Jview) it makes a nice desktop background for OS/2. The .PNG is in 1024x768 and 256 colours.
This bitmap is of course public domain, so use it and abuse it to your heart's content.
