Standing Bear immortalized on postage stamp.

Chief Standing Bear, a leader of the Ponca tribe, who fought for Native American legal rights in the US, has been honored with a Forever stamp featuring his portrait. His 1879 lawsuit ensured that Native Americans were considered persons with inherent rights under the law. The illustrated portrait on the stamp was based on a black-and-white photograph taken in 1877. The stamp serves as a symbol of pride and perseverance for all members of the Ponca tribe and etches his legacy in the national consciousness.
