Katakimaankwa was a Myaamia observer sent by his community to watch the signing of the Treaty of Prairie du Chien in 1825. James Otto Lewis painted his portrait at some point during the negotiations. Note the lightly marked triangle patterns of the edge of the garment covering Katakimaankwa’s shoulders. It is likely this was a geometric pattern. Based on the color of the material, it is possible that these designs were produced by the appliqué of dyed and cut pieces of hide. This technique can be observed on the leggings in the case to the left.
