Travel blogger Bill Passman has documented his journeys across the world in quite the unusual way. In 2010, and inspired by a woman with a similar design, the travelling backpacker got a large tattoo of the world map on his back – colouring in the places that he had visited. “While sitting in the Pirate Bar in Utila Honduras waiting for the World Cup to begin, I quickly noticed a girl, Jules, who I had met earlier in Antigua” he wrote on his blog. “After speaking for a moment she quickly turned around to speak to someone else and that is when I noticed it, a tattoo outline of the world. I, along with many other backpackers, quickly told her how awesome it looked. “She also said that she planned putting a red dot on all the places she has traveled. While sitting at the table looking almost hypnotically looking at her tattoo every time her back was facing me, I realized that I had finally gotten the inspiration for the "travel" tattoo that I had been thinking about since my trip to Thailand.” Here are some of the shots of the tattoo, with Passman adding new colours along the way: Now that’s dedication!
