“Show us our butts! Mucawana tribe – Angola. In Soba village, the Muhacaona (Mucawana) tribe, perhaps the best place i have visited. They use cow dung and fat to make this so nice haircut, and love the beads. They asked me to make pictures of their backs... and butts to see on the camera screen if everything was perfect!”.

Trees grow through the windshield of a 1937 Chrysler Imperial as it sits at Old Car City, the world's largest known classic car junkyard Thursday, July 16, 2015, in White, Ga. Over 4,000 classic cars decorate 32 acres of forest which have been turned into a junkyard museum by owner Walter Dean Lewis. The two grew up playing in the cars on the lot which started as a general store selling auto parts in 1931 by Lewis' parents. Lewis stopped selling parts about six years ago when he realized he could sustain the business more as a museum, charging $15 for visitors just looking, and $25 for photographers. Many of the cars have never moved in over 30 years and in some cases, trees now grow through them, even lifting some off the ground. (Photo by David Goldman/AP Photo)

Beneath the Swedish capital lies an intricate web of underground train lines. More than 90 of the 100 stations in the 110km tunnel system, sometimes referred to as “the world’s longest art gallery”, have been decorated with paintings, installations, mosaics and sculptures by 150 artists since the 1950s. After spending a couple of weeks exploring arctic Norway and Sweden, London-based travel photographer Conor MacNeill headed underground to capture images of the metro stations.

The impressive gallery shows beautiful landscapes that might appear to be from more exotic climes, but they were all taken on British soil. Alessio Putzu, 31, a professional landscape photographer from London, snapped the amazing shots during his trips to Devon and Cornwall, England; Pembrokeshire, Wales; and the Isle of Skye, Scotland. Here: Bedruthan Steps, Cornwall. (Photo by Alessio Putzu/Caters News Agency)
