Sorry Inger, but we've done that joke once this week:
it's not the length of your experience that matters, it's what you do with
it.

Best alike down to the gutter between pages? I don't think so.

How was the Vinland Map cartography of the Old World copied from the Andrea
Bianco map with different scales in different areas, and trapezoidal
distortions of shape throughout.

And while we're on the subject, why was the portion of Africa below the
page gutter not copied?

I can think of one very good and simple reason for all these phenomena- but
it's not a medieval reason, so I want somebody else to supply one (or
several, if need be). If nobody can, then this is pretty convincing
evidence that the Vinland Map is a fake.
