Summary
This file is highly derivative of an image originally found on Wikipedia. It has now been changed to the point that the uploading editor (CzechOut) asserts it to be a novel work. The original file was either licensed under the CC-BY-SA 3.0, or flatly in the public domain. This version, believed different enough that CzechOut claims authorship, is now released under the CC-BY-SA 3.0 license.
