He fought in the First World War in the Artists Rifles[5] From 1923 to 1943 Purvis worked for the London & North Eastern Railway (LNER)[6] under the direction of Advertising Manager William Teasdale and then his successor Charles Dandridge, who both allowed him considerable freedom in his designs.
His posters for the LNER largely avoided depictions of the trains themselves but rather concentrated on portraying the resorts that were the holiday destinations of travelers and the leisure pursuits that could be enjoyed there.
Sex appeal was quite a strong element of Purvis's work, with many posters portraying women in bathing costumes with bare arms and legs—quite risqué in 1930's Britain!
[7] The ... by LNER series portrays six seaside resorts, each shown at an unusual angle, to form a continuous landscape in the background as the posters, like the trains themselves, travel up the east coast of Britain from Essex to Suffolk, Lincolnshire, Yorkshire and finally Northumberland.
As well as his work for the LNER, Purvis also designed posters for the Gentlemans' outfitters Austin Reed and for the 1932 British Industries Fair.
