This is what I'm talking about.
This one below is already an improvement over what we had in 2000-ish. It's just hard to find the older ones, and I'm not putting hours into finding maps that are more wrong.
Worth mentioning that many of the uninhabited areas of Africa were made so by the slave trade, so it's not an error to have them shown as uninhabited even when we know they had ancient populations. But Australia was not uninhabited, North America definitely wasn't, and
most of Africa had people too (and a lot of them were iron working farmers). Uninhabited here is clearly meant to represent unorganized, so it's not that bad. Credit should definitely go to the people who made the updated versions Next-Gen OTL WorldA, it's all part of the process.
Point being is that they get better all the time.
edit - actually here is one from even earlier that is a bit less accurate
it's a map of 1770, not sure when it was made or who made it, I found it on duckduckgo image search for 'OTL basemap'
