Well, many of the flags of the Soviet Republics were basically the same as well. And of course many of the US state flags (SOB). The similarity might simply be due to laziness, but it is quite realistic as well.
Nice and well thought out flag! It ticks all boxes for a good design.
I think I prefer this to the most famous keystone proposal. Putting the keystones in the middle make them more clearly look like keystones, rather than just a strange middle field. Matching William Penn’s coat of arms is also a nice bonus.
No idea why it’s a gif. I just linked to it from that webpage. It doesn’t display a play symbol in the browser. But it is a good call from you, showing why it’s better to avoid gifs for static image. Nevertheless, the position of the play symbol is quite pleasing.
Glad to see this series here! I hope you keep posting!
Regarding the Cabinda flag, it seems to me that the color combination is not working too well. Maybe because its not very “vexillogical” colors? Yet, orange and blue are supposed to work well together, but maybe the yellow in between ruins the effect?
Yeah, I agree. I also prefer the version where they did not change the green or the bending of the crescent. Apparently that was the initially presented proposal.
According to Wikipedia, ingots looking like that, Katanga crosses, has historically been used as currency in the region. It is included in the flag as a symbol of prosperity.
