This is a flag of the Japanese Mindan Organization, unfinished because I couldn't get the flower correct. Anyone good at drawing symmetrical hibiscus syriacus flowers? Please update this image. I just thought if I didn't upload this now in it's unfinished state, I'd never get around to uploading it or ever fixing it to final status someday. This is based on not free images of this flag (although all art is mine or based on free use images) that were found at: [1] and [2]
