UnicornFork's chess pieces (web/src/pieces/) are Colin M.L. Burnett's (Cburnett on Wikimedia Commons): his own last versions, uploaded on 3 January 2007, of File:Chess_klt45.svg, File:Chess_kdt45.svg and the other ten files (https://commons.wikimedia.org/wiki/File:Chess_klt45.svg), unchanged but for their names. sprite.svg puts them together for the boards, their drawing only, its style attributes as presentation attributes (chessgpt/pieces.py). He offers them under the license of your choice of the GFDL, the BSD license and the GPL. UnicornFork uses them under the BSD license:
