The 414 marker tree is a tribute to the Native American Menomonee in the Milwaukee area and the upper Mid-Western native populations. All proceeds from the sale of this t-shirt benefit the Indian Community school. Directional, trail marker trees, crooked trees, prayer trees, thong trees, or culturally modified trees are hardwood trees throughout North America that Native Americans intentionally shaped with distinctive characteristics that convey that the tree was shaped by human activity rather than deformed by nature. 100% cotton shirt.
