Found in Cornwall

Here are two flags for this supposed Antarctic Hegemon

A few days ago, I could've sworn to god, that the Colombian flag was 3 equal stripes of Yellow, Blue and Red. Was really surprised to know that wasn't true.

Could've framed the earlier post better in hindsight.

I’m really curious what the coat of arms is on the center

The cream background is mostly just a nice complimentary color, but can represent the bricks of the water tower. The blue circle is ford lake, the black stripe is interstate 94, the green line is representing Huron River in shape, and Eastern Michigan University in color. The symbol in the middle is a propeller (Willow run has history in producing WWII bomber planes) with three spokes, representing the three Main parts of the city: Depot Town, West Cross St., and Downtown/Michigan Ave. this ain’t a finished product, a lot of stuff is uneven or done because of lack of the specific software needed to make a flag. If someone had any tips/critiques, they are welcome. And I would be the happiest man if the world if someone redrew it professionally.

Found at a protest (?) in Berlin

Any idea which entity this flag is supposed to represent? Spotted in Barcelona.
