Summary
This is an intentionally faked symbol
This symbol is fictitious and is useful only to facilitate visual identification of some articles within Wikipedia. This symbol has some visual elements that are similar to its official counterparts, such as colors or some shapes, but they are NOT official and don't have any direct relation to the official source.
The official symbol cannot be uploaded to Wikimedia commons because they are protected by authorial rights (copyright); in this way, if you want to localize the official symbol, try to contact its official source and ask for the official symbol and a possible license of use for your purpose.
This image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file “InfoboxHez.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
