Joseph's best known poem, 'Warning', was written in 1961 and is included in her 1974 collection Rose In the Afternoon and The Oxford Book of Twentieth Century English Verse.
'Warning' was identified as the UK's 'most popular post-war poem' in a 1996 poll by the BBC. The second line was the inspiration for the Red Hat Society. Due to its popularity, an illustrated gift edition of 'Warning', first published by Souvenir Press Ltd in 1997, has now been reprinted 41 times.
