Find the map with borders here: https://scratch.mit.edu/projects/312796314/ ---------------------------------------------------------------------- This is what it says it is. Do not press green. Do not see inside. There is nothing else to see. This is the map I'm using for my Mapping history series (https://scratch.mit.edu/projects/111469944/), and I thought it would be better to share it so that other people could use it as well. If you want it for a project, just press see inside and put the backdrop into your backpack.
I took the map off Google and did a big clean-up on the sea borders (defining the border, getting rid of grey bits etc.), a job which took several hours. It should be (mostly) accurate.
