Between early 2020 and spring 2021, Oxford - like the rest of the UK - was subject to a series of restrictions to combat the spread of the pandemic. After initial hesitation, the government stipulated that face masks should be worn in certain contexts to reduce transmission. These masks soon became obligatory but also a matter of personal choice in terms of how they looked and what they signified. Over a year, Oxford based photographer Martin Stott recorded hundreds of images of masked individuals in the city, revealing the extraordinary diversity and individuality at play in a public health measure that was previously unfamiliar to most people. Politics, identity, fashion, subversion and resilience are all colourfully expressed in Stott's subjects who were photographed in a range of everyday contexts. This book presents 56 of these photographs. Wear a Mask!, echoing Anthony Fauci's memorable plea for collective action, provides a striking visual record of how Oxford's population reacted to an unprecedented public health crisis and turned face masks into a powerful expression of identity.
