The Witcher franchise is so popular in Poland, where its developer is headquartered, that the country's prime minister gave a copy of The Witcher 2 to President Obama back in 2011. Now, the nation is celebrating the franchise in another way--by releasing a postal stamp with Geralt of Rivia on it.

CD Projekt Red's Damien Monnier released an image of the stamp on Twitter (via VideoGamer.com). Someone responded to the tweet by saying The Witcher is Poland's biggest pop-culture export. Monnier said vodka and pork products might come ahead of The Witcher, but all the same, having a Witcher stamp is "very humbling."

In 2014, Obama specifically mentioned The Witcher series during an appearance in Poland. Obama said the acclaimed role-playing video game series developed in Poland is a "great example" of how the country contributes to the global economy.

The Witcher is arguably the most well-known video game series ever to come out of Poland. Other big-name Polish studios include The Farm 51 (Painkiller), Techland (Dead Island, Dying Light), and People Can Fly (Gears of War: Judgment).

CD Projekt Red's fantasy Witcher series is based on Polish author Andrzej Sapkowski's novel series of the same name.
