A visitor takes a picture of a display bearing hand prints of war heroes from the War of Resistance against Japan, at Jianchuan Museum Cluster in Anren, Sichuan Province, China, May 13, 2016. Tucked away in southwestern China's Sichuan province, a private collector stands virtually alone in exhibiting relics from the 1966-1976 Cultural Revolution. Monday marks the 50th anniversary of the start of the political movement, with no official commemorations planned. Official records whitewash the details of both periods, but admit that Mao made major mistakes. (Photo by Kim Kyung-Hoon/Reuters)

“Einar Erici (1885–1965) was a physician by profession, working at a tuberculosis hospital in Stockholm, even running a private medical practice. He was by then the most renowned Swedish expert of church organs and organ builders, and his archival collection is today held by the Swedish National Heritage Board. This archive includes mostly writings, such as letters and manuscripts for published articles and essays, but also more than 2 000 black and white photos – original prints, glass plates and film negatives”. – Swedish National Heritage Board

A man holds up for a picture a one hundred trillion Zimbabwean dollars note inside a shop in Harare, Zimbawe, June 12, 2015. Hyperinflation in Zimbabwe was a period of currency instability that began in the late 1990s shortly after the confiscation of private farms from landowners, towards the end of Zimbabwean involvement in the Second Congo War. During the height of inflation from 2008 to 2009, it was difficult to measure Zimbabwe's hyperinflation because the government of Zimbabwe stopped filing official inflation statistics. However, Zimbabwe's peak month of inflation is estimated at 79.6 billion percent in mid-November 2008. (Photo by Philimon Bulawayo/Reuters)

“The series of photos called Workwears, by French photographer Bruno Fert, visually juxtaposes people’s private lives with their lives at work. A firefighter, a fisherman, a nurse, a diver, a judge. One by one, Fert’s photos show people in their homes wearing everyday clothing – followed by another photo showing them dressed in the clothing of their chosen professions. Our reaction, Fert said, reminds us how tightly humans hold on to certain stereotypes about some professions. “I like to break those stereotypes”, he said”. – Thom Patterson via CNN.

Drawn from Scotland Yard's private collection, the show charts more than a century of violence and suffering, from the murders of Jack the Ripper to IRA and al-Qaida bombings. But it also celebrates the brains, bravery and scientific advances that helped catch perpetrators and solve crimes. (Photo by Alastair Grant/AP Photo)
