Portrait of Ann was seen as a major departure from Lowry's stock images of industrial scenes and millscapes — not least because Lowry very rarely used women as his subjects. Lowry described the style of the painting as being "modernist", explaining that the sitter "did not want her picture to be realistic; it had to be stylised." In common with Lowry's other oil paintings, Ann was executed using ivory black, vermilion, Prussian blue, yellow ochre and flake white with no medium. Upon its eventual exhibition, the painting was criticised by the art critic G.S. Whittet in the August 1958 edition of The Studio as having a "crudely stylised face", but it was not without its supporters; Nesta Ellis, writing for the Sphinx art journal, thought the painting "gave the impression of an impassive yet wilful woman". Ann was never sold at auction, but instead remained the property of the artist until it was bequeathed to Salford Museum and Art Gallery upon his death in 1976.
