Yvette Coppersmith has won the 2018 Archibald Prize for her self-portrait.

The work, titled ‘Self-portrait after George Lambert’, was chosen from among 57 finalists. The decision, made by the Art Gallery of NSW’s board of trustees, was unanimous.

“Yvette is a highly talented young artist who brings a deep and historical understanding of the tradition of contemporary art practice,” said the gallery’s director Michael Brand.

Coppersmith was also a finalist last year with a portrait of Gillian Triggs.

There were 21 self-portraits this year in the prize, a number which Brand said more than doubled the figures of recent years.

The Wynne Prize for landscape painting or figure sculpture went to Yukultji Napangati, while Kaylene Whiskey was awarded the $40,000 Sulman Prize her work ‘Kaylene TV’.
