Still Life with Tulips by Samuel John Peploe. It’s dated 1920-30 because Peploe (who has a Persephone link because D E Stevenson was his niece by marriage ie. her husband was his nephew) painted tulips so often that many of his paintings cannot be accurately dated. But this has an indefinably ’20s look (glad not to be a history of art undergraduate and having to explain that indefinableness).
