The first twelve stamps, the low values up to 1 shilling, were issued during 1922–1923, while the three high values, 2/6, 5/- and 10/-, did not appear until 8 September 1937. Designs included: "Sword of Light", "Map of Ireland", "Celtic Cross", "Arms of the Four Provinces" and "St. Patrick". Watermark and extra values were made until new designs, known as the "Gerl definitives", using early Irish art motifs, were produced in 1968. These were the first new designs in 31 years for the high values and 46 years for the low values. The Gerl series was denominated initially in pre-decimal Irish pounds and later in decimal currency (both watermarked issues). It latterly appeared as unwatermarked stamps.
