Design Factory's brief was to design a set of 2 stamps for An Post's annual Europa stamp issue. An Post work in conjunction with most European Post Offices on this project. The subject matter for 2014 was national musical instruments. The Irish harp and an Irish bodhrán were chosen for the stamp set. A rare Egan harp from the National Museum of Ireland and the bodhrán belonging to the late Éamon de Buitléar were used in the 32mm square designs. In addition, stamp sheets were designed featuring a detail of each instrument.
