She will join a hall of fame of Swedish personalities, from Zlatan Ibrahimovic to Greta Garbo, who have been depicted on the country's postage stamps.
The stamps go on sale from PostNord on Thursday and show Thunberg in her familiar yellow raincoat standing on a rocky coast looking out at a flock of birds, according to Reuters

Several million of the stamps will be issued, Olofsdotter said, adding: "There will be a lot of Gretas flying around."
Thunberg rose to global fame in 2018 after she began skipping school to protest, alone with a homemade sign, outside the Swedish parliament in Stockholm, demanding that her government take action on climate change.
Within months, more than 2 million students in 135 countries had set up their own picket lines, joining Thunberg's "School strike for the climate" campaign.
In 2019, Thunberg took a year out from school to cross the globe by car, train and boat – but not plane – to demand action on climate change, a trip that involved a brush with US President Donald Trump and a speech at the United Nations climate summit.
