I read on the author's website that the Badly Drawn Map is a real map, namely, the Mappa Mundi that is on display in - I think - Hereford.Dang. that's annoying. I totally thought it was the board game Risk.
I hope I never ridicule what is wise or good. Follies and nonsense, whims and inconsistencies do divert me, I own, and I laugh at them whenever I can.
