It would be fascinating to know what international talks/agreements took place to determine which country would use what markings.
I’m sure someone with knowledge of this subject will contribute.
A cease fire was called, and a “best of 3” game play-off of “noughts and crosses” was used to decide “who used what” for national markings.
Of course they had to toss a coin to see who went first, and who was the “nought”.
