Yeah. I guess Leo could've been a member here. Pretty cool, and not so far from the style of a few of our members. I do wish it was a 1:1 scan, though, so you could see the detail. Do you know the provenance of this map? Is it in a museum or a private collection? I really dig his city icons and would love to see those guys close up. Think the numbers are altitude?

As to medium? No real idea. I'd guess parchment and ink?
