Openclipart

Openclipart uses the Creative Commons Zero 1.0 Public Domain License every time
an artist uploads a piece of clipart to Openclipart to make it clear the artist
is releasing the creative work for anyone to use for any reason, even
commercially. This act of "sharing" is the foundation Openclipart is based upon.
More details on the license can be found at
