Other than the odd ratio of the circle to the whole flag, why the outline of the circle is there? Also, I said it's a fake just by the red circle. There are too many slogans there, with almost every signature. One of them 銃後女性 is not even a slogan in the first place (this is a description about women at the era). You can see how many fake flags are made and sold in the world even in this forum.
