"In the 2006 offseason, the [Spokane] Indians began a process to redesign their logo and uniforms. As per tradition, they began by avoiding the use of any American Indian imagery, but early in the process of redesign, the Spokane Nation contacted the team about officially supporting the team. In the process, the tribe gave permission to the team to adopt subtle and tasteful imagery, in order to pay homage to the team’s history and new connection with the tribe. The cooperation, called "historic" by the team, included the creation of a secondary logo written in Salish, the traditional language of the tribe."
If you’re gonna do it, this seems to be a pretty good way to go about it.
