In this photograph received from the South China Morning Post (SCMP) archive on May 2, 2017 and taken on May 16, 1967, protesters (R) wave the Little Red Book “The Quotations from Chairman Mao Zedong” in front of police outside the South Kowloon Magistracy in Hong Kong. Hong Kong is unrecognisable now from the city which 50 years ago was the scene of bloody riots, fuelled by resentment of colonial rule and inspired by the Cultural Revolution unfolding in China. But although memories of the bomb-strewn chaos of 1967 have faded, the city is facing a new era of turbulence as democracy activists take on Beijing and many ordinary residents still struggle to make ends meet.

An employee of the David Goldsmith factory sandpapers the curves of a mannequin before applying a coat of paint in New York, July 7, 1942. David Goldsmith operates a factory which makes realistic window models of pretty girls for the display of clothing and hats. That in itself is not unusual, but when he places the nude figures in his show window for all the world to see, he invites the wrath of reformers and the curious stares of passersby. During the Lindbergh baby kidnapping case, he was almost arrested by policemen at the George Washington Bridge. They stopped his car and in a routine search uncovered the plaster model of a blonde-haired boy. One of them mistook the model for the Lindbergh baby and with a drawn gun collared Goldsmith.
