Michael Collins by John Lavery (1921).

In 1922 Sir John Lavery painted two famous portraits of Michael Collins and Arthur Griffith (below) while both were in London as part of the delegation of the Anglo-Irish Treaty talks. Collins was an Irish revolutionary leader, Minister for Finance, Director of Information, and Teachta Dála (TD) for Cork South in the First Dáil of 1919, Adjutant General, Director of Intelligence, and Director of Organisation and Arms Procurement for the IRA, President of the Irish Republican Brotherhood from November 1920 until his death, and member of the Irish delegation during the Anglo-Irish Treaty negotiations. Subsequently, he was both Chairman of the Provisional Government and Commander-in-Chief of the Free State Army. Griffith was also part of the delegation that signed the Anglo-Irish Treaty in 1921.
