[2] As well as working as a painter and draughtsman, Hey also modelled for the artist Walter Sickert who painted her portrait several times in the early 1920s.

[4] The large number of drawings and paintings Sickert produced of Hey included a double portrait of the pair of them, Death and the Maiden.

[4] Sickert gave Hey a large number of paintings and drawings which she donated to the Whitworth Art Gallery in Manchester shortly before she died.

[4] At the time Hey met Sickert she was living in a house in Bloomsbury which she shared with, among others, Robert R. Tatlock, an art critic and long-time editor of the Burlington Magazine, who she later married.

She would work in terracotta, wire and paper mache to create miniature period figures often with historically accurate costumes.
