In 1939 Keating was commissioned to paint a mural for the Irish pavilion at the New York World's Fair. He was President of the Royal Hibernian Academy from 1950 to 1962, and showed at the annual exhibition for 61 years from 1914 onwards. Keating was an intellectual painter in the sense that he consciously set out to explore the visual identity of the Irish nation, and his paintings show a very idealised realism. He feared that the modern movement would lead to a decline in artistic standards. Throughout his career, he exhibited nearly 300 works at the RHA, and also showed at the Oireachtas.
