Not far from the refurbished F1 race track of Kyalami in Johannesburg, South Africa is a small, virtually dirt race track that attracts only the brave and rare ‘petrol heads’ on some Sundays to race against each other in the hot sun for bragging rights and a trophy. The track is home to the Walkerville Sppedway Racers Club that includes flat track racers, sidecar racers and a new breed; the Stof Kop (dust cup) racers. [ 15 photos total ]

In May of 1870, Thomas Child was hired by the Imperial Maritime Customs Service to be a gas engineer in Peking (Beijing). The 29-year-old Englishman left behind his wife and three children to become one of roughly 100 foreigners living in the late Qing dynasty's capital, taking his camera along with him. Over the course of the next 20 years, he took some 200 photographs, capturing the earliest comprehensive catalog of the customs, architecture, and people during China's last dynasty. On Thursday, an exhibition of his images will open at the Sidney Mishkin Gallery in New York, curated by Stacey Lambrow. In addition, descendants of the subjects of one of his most famous images, Bride and Bridegroom (1870s), will be in attendance. [ 20 photos total ]
