Avery Jackson, a young transgender girl from the US, will feature on the cover of National Geographic's first 2017 issue.
On the cover, nine-year-old Jackson is quoted as saying: "The best thing about being a girl is, now I don’t have to pretend to be a boy".
The issue's theme is "Gender Revolution" and features the stories of young people who identify as transgender and gender non-conforming, and looks at the impact of friends, family and community on trans and non-binary people.
Jackson will feature on the subscriber edition, while the newsstand version will feature a group shot.
Although only nine years old, Jackson has been a vocal activist for transgender equality for years.
Earlier this year, she took on the Westboro Baptist Church with a successful crowdfunding campaign that allowed her to purchase a house two doors down from the church, paint it the colours of the transgender pride flag, and create a place of love and support for the trans community in Kansas.
