This is basically the flag or technically one of the two well-known group Flags (in universe) the red white and blue mean nothing, but the stars do mean something. the question mark and then the star right next to it supposed to symbolize how many state countries there are (honestly don't know what to call them) The big star symbolizes being Unified

The middle one is just this country with no name but drawn in the same way I draw California

Another fact about the flag design it's slightly based off of the United States flag the whole star stuff and the blue rectangle in corner of it (the history of the country kind of is just British colony stuff Plus of Independence too)
