National Geographic has offered a strikingly visual, yellow-bordered window into the rest of the world for 125 years — and to celebrate the anniversary, they are auctioning off 125 images from their archives through the Christie's site, from July 19-29. Here are 15 images from "Boundless: 125 Years of National Geographic Photography."
