"London Types: Costermonger" is a color lithograph by William Nicholson that depicts a street vendor characteristic of late 19th century London. The work exemplifies Nicholson's bold graphic style and his interest in capturing the diverse social types and working classes of urban life. Created as part of his London Types series, the print combines simplified forms and flat areas of color typical of the lithographic medium to convey the distinctive character and costume of a costermonger, or street fruit and vegetable seller.
