These pictures were taken in 1877 by photojournalist, John Thomson. He was a pioneer of his time, shunning images of British aristocracy and scenic landscapes and opting to show the harshness of city life for millions of working class people in London.
Among the subjects he photographed were street vendors, child labourers, shoe shiners, disinfectors and chimney sweeps. Within a year, Thomson had produced 36 photographs which were published on a monthly basis.
Images depicting the life of London's Victorian working class will be sold at Dominic Winter Book Auctions in Gloucestershire this Thursday.
