Day was perhaps best known during the 1950s for working with the textile company Heal's, but the designer also produced patterns for other companies, including this design for British Celanese Limited. Day designed Perpetua for the company in 1953, which continued the 'contemporary' style she had become known for, after the success of her prints at the Festival of Britain in 1951. British Celanese Limited were one of twenty-six British manufacturers that were recruited by the Festival Pattern Group to promote 'good' design. The vividly coloured patterns in Day's designs were inspired by abstract artists like Paul Klee and Joan Miro, and Day sought to create a similar energy with her prints.
