It also boggles my mind:
1. How accurate it was, in terms of map fidelity
2. The quality of the illustrations and prints, many of which are in several (what I imagine was offset?) colors!
3. How well it's held up. The cover looks essentially completely trashed, but the interior of the book's pages are almost entirely intact, and in great shape. (I'm not worried of them turning to dust in my hands, for instance.)
It's always fascinating to see just how little has changed, especially among schoolkids in nigh on 300 years!
Here's essentially the exact book I'm talking about, so it's not _that_ uncommon. Looks to be in almost identical condition, too: https://www.ebay.com/itm/184283104558
