This is a vector reproduction of a png icon from the Nuvola icon theme for KDE 3.x.

I created it without realizing that an svg by the original creator is also available.  But perhaps someone will find this version useful.
Original Nuvola icon: http://www.icon-king.com
SVG adaptation: created by uploader
Original Nuvola icon: David Vignoni
