I mean.

The artifact you link shows a map of the Americas in which California is an island and either Tierra Del Fuego is huge or the bottom of Argentina is an island and the northwest of the continent trails off into nothing, and Florida is sort of a stubby nub (other maps from this period show a more accurate Florida, so this might be a small-size-of-the-object problem).

They had a decent view onto the east coast of the Americas, but after that things got quite inaccurate. It's like... I don't know what anyone's expectations are, but it certainly isn't the perfect world map that's shown in the main image of Wikipedia's article.
