Martinique’s Council finally approved an offiial flag for the region, after the last design’s adoption was annulled.
Martinique’s flag
From what I’ve read this design is to be used on par with the French flag, the latter taken precedence over the first, but for sporting and cultural purposes the new design may be used.
So if there’s no inconvenience, and pending further news, I suggest to replace the current icon in the forum.
