June 21 is National Selfie Day, an unofficial holiday founded in 2014. National Geographic is celebrating by sharing a gallery of selfies from their photographers and explorers. You can't beat selfies taken in a wilderness, jungle, or war zone, selfies taken with Vikings or pandas, or during death-defying activities. Strangely, there are two taken during haircuts! Shown here is photographer Gerd Ludwig, who visited a cosplayer couple in Moscow who have a friendly pet owl. See the amazing gallery of selfies at NatGeo.
