National Geographic is taking a historic step for transgender visibility. The magazine will feature 9-year-old transgender girl Avery Jackson on the subscriber cover of its January 2017 issue.

Entitled “Gender Revolution,” the issue accompanies a documentary developed in partnership with Katie Couric for the National Geographic Channel. The film explores the transformative role of gender in everyday life from genetic, cultural, and neurological perspectives. The documentary will air Feb. 6

Avery’s mother, Debi Jackson, a Republican and Southern Baptist, shared her daughter’s story in a 2015 YouTube video diary and a GLAAD video series. She also delivered a powerful speech in a 2014 episode of the Kansas production “Listen to Your Mother.”

“The one thing that I impart upon my daughter is very simple: Love yourself and show love to others,” he writes. “That is exactly what I intend to do. I love my daughter for who she is without preconditions, and I promise to help nurture her into a becoming a happy, healthy and productive member of society. After all, isn’t that our job as parents?”
