It's a bold design Agree. I think it would rank high on a graphics-design ranking alone, never mind what it may or may not stand for.
Bold primary colors, symmetry, good-sized stars, and an X-pattern. What's not to like?
I study flags and even as a northerner I can say it is really well done. Almost too good from a time where most American state flags were pretty bland and carelessly tossed together and the national flag had no standard design.
And it actually made other flags look better. When attached to them.
