This is the 256×256px "Vista" design, which was not incorporated into the ICO files due to size concerns. Nonetheless, the Xara LX source vector was added to the Python source tree in <a rel="nofollow" class="external text" href="https://github.com/python/cpython/commit/8301c7923ddc90b23b8ab37c29eba6cd5df06669">commit 8301c79</a> (an SVG conversion exists in the source zip but is exceedingly subpar, and was not added to the Python tree).
