This is a complete set of the renowned 'Gerl Definitivee Set' of Irish Stamps. In 1966 the Irish Government held an international for new designs for a new definitive set of stamps. The winning designs were submitted by the German artist Heinrich Gerl. The designs were based on motifs from ancient celtic art. The four designs were 1, Dog, based on a broach in the National Museum of Ireland. 2, Stag, from a bowl in the British Museum. 3, Winged Ox, from the book of Lichfield. 4, Eagle from an ancient Irish manuscript in the library of Corpus Christi College. Following Decimalisation in 1971 the designs remained but the denomination changed.
