The GNU Press Shop is proud to present the 2020 LibrePlanet t-shirt in a very handsome shade of muted aquamarine. The LibrePlanet 2020 depicts the partnership of human and machine for the advancement of freedom, which is the theme of this year's conference. It's very attractive, and when you wear it people will ask you, "How was the conference?", and you can say it was excellent.
The shirts are manufactured by Bella Canvas, which is WRAP-certified, meaning they comply with ethical, health, and safety standards in manufacturing. Information on their environmental practices is here.
