This image was drawn by Christian Siemer [1] according to a description based in the German book Flaggen-Wappen-Daten by Karl-Heinz Hesmer (1947-2013). Short before his death user "Antemister" asked him for the depiction he used for his description. He told user "Antemister" then that this image is not 100 per cent accurate, but did not provide me further details. He died suddenly before user "Antemister" could ask him about further details. Since then, user "Antemister" claims to know that this image is not fictional, but also not really correct.
