National Geographic is celebrating its 125th anniversary by sharing some extraordinary images from its archives on a new Tumblr site called Found. Many of these photos have never been published and are rarely seen by the public- they range from black and white photos of the 1900s to early colour images of the 1930s and star all sorts of nationalities, moments from the past, animals and curiosities. National Geographic said: “We hope to bring new life to these images by sharing them with audiences far and wide. Their beauty has been lost to the outside world for years and many of the images are missing their original date or location.”
