Manabí, since 2007
The flag of this Ecuadorean province has a somewhat unusual composition. Arcs of stars are pretty standard, but they aren’t usually spread over multiple stripes or put next to a triangle like this. The whole thing just feels weirdly asymmetrical and unbalanced.
There are some images online that show the stars in a circle instead of an arc. That would make a lot more sense, but the version with the arc seems way more common, even when you discard the renderings on FOTW and Wikipedia.
