In "Going Postal" (and other books before that, mainly Watch books) it says Which got me thinking a little, because on all the pictures I could find - for example in the Discworld companion - you could vaguely see something, black on black, so to say. I am referring to this pic: It may be coincidence, but I can make out a diagonal bar, which, in heraldry, could mean that you were a bastard acknowledged by the father, allowed to carry the name and step in as an heir, and the diagonal line was just added to the usual coat of arms. It happened quite often - the historical Leonardo da Vinci was such a case, I seem to remember. Do any of you more detailed or different description of the coat of arms? Or other pics?
