The Armorials section in Wikipedia:

The armorials of the South Sea Company, according to a grant of arms dated 31 October 1711, were: Azure, a globe whereon are represented the Straits of Magellan and Cape Horn all proper and in sinister chief point two herrings haurient in saltire argent crowned or, in a canton the united arms of Great Britain. Crest: A ship of three masts in full sail. Supporters, dexter: The emblematic figure of Britannia, with the shield, lance etc all proper; sinister: A fisherman completely clothed, with cap boots fishing net etc and in his hand a string of fish, all proper.[61]

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.
