Rank Badge with Crane

The Rank Badge with Crane by unknown artist shows a black square with a white border. The black background is filled with intricate white swirling patterns. A white bird, likely a crane, is centered, facing left, with wings spread. The bird has a detailed feather pattern, a long neck and legs. The bird appears to be flying or in mid-stride. The swirling white patterns resemble clouds or waves. A sun or circle design element is at the top center. The overall design suggests it is a rank badge.
