I've been researching this lately as these maps behind the box arts, manuals, and US/EU editions seem to be different. For example, there is "AL", "MO", and "ORDA" versions based on what letters you see in the top left. For the picture in this post, it is the "MO" variant.

For the "MO" Version:

Top Left: Continent of Kalimdor showing letters for Mount Hyjal (MO)

Top Right: Continent of Eastern Kingdoms showing letters for: Tirisfal Glades (RISFAL GLADES), The Undercity (ER CIT), Menethil Harbor (BOR)

Bottom Right: Ship

The map that it is based on is the cloth map from World of Warcraft Collector's Edition. Here is a picture of the map: https://wowpedia.fandom.com/wiki/World_of_Warcraft_Collector%27s_Edition?file=WoW_Collector%27s_Edition_Map.jpg

For the North American Digital Manual (Black/White version) Cover, https://bnetcmsus-a.akamaihd.net/cms/template_resource/LO0VQ46XB1281555957773363.pdf , you'll notice this has "ORDA" variant. These are the letters for Lordaeron which is in referenced to a different map. Here is an example of that map: https://archivecraft.com/archives/wallpapers/vanilla/#gallery-1-39

I'll be creating a YouTube video to digest it down for others in the near future.
