[citation needed] In 1996, Hanley visited Bosnia and Croatia with the Irish Defence Forces, conducting research ahead of producing a painting to commemorate Ireland's leadership of the European Union Monitoring Mission in the former Yugoslavia; the resulting picture hangs in the military college at the Curragh Camp.
In 2006 he designed a coin to mark the 175th anniversary of the Irish Office of Public Works and in 2007, he was the artist in residence at the Centre cultural irlandais de Paris.
He was commissioned by the Irish post office to design three Christmas stamps for 2008.
[1][2] Hanley's work is held by the National Gallery of Ireland, the Irish Museum of Modern Art, and in the collections of the Office of Public Works and the Arts Council, from which it can be loaned to Irish State offices and agencies.
Works are also held by his alma mater, UCD, by the University of Limerick, AIB Bank and the Irish National Lottery.
