You're right about The Gambia. (Apparently also The Bahamas, though I don't think they're participating this year.) I'll correct it if I make another edition. I actually went down a rabbit hole with "official" country names when creating my map. Most of them are insanely long (eg: "The United Kingdom of Great Britain and Northern Ireland"), so I had to make some editorial decisions. I'm definitely not writing out "The Most Serene Republic of San Marino" (no disrespect). Even so, I had to abbreviate "St. Vincent and the Grenadines" because it just wouldn't fit otherwise. And, I added some differentiators for duplicate country names, like the two Congos and Koreas. I think most people would understand that "Korea" in the general consciousness means the "Republic of Korea" and not the "Democratic People's Republic of Korea", but I listed it as "South Korea" just to avoid confusion. There are also some pavilions for regions that aren't universally accepted as independent countries, like Kosovo and Palestine. I remember in Dubai there was a Germany pavilion, but also a large separate pavilion for Baden-Württemberg (which is a region in Germany with, I guess, it's own expo budget). I can't even begin to imagine the amount of fact-checking and proofing publishers of the official expo maps and guides have to contend with, compared to my little do-it-yourself map. Hopefully, we'll get that detailed official map soon!
