Between 1982 and 1988 a series based on Irish architecture through the ages was released, with line drawings by Michael Craig and graphics by Peter Wildbur. It contained twenty-eight stamps, with values ranging from 1p to £5. Stamps based on Irish cultural heritage followed between 1990 and 1995. Irish birds feature in the 1997 series that span the conversion of currency from the Irish pound, through dual currency to the introduction of the Euro. These were the first definitives where all values were printed in full colour. On 9 September 2004 new stamps, featuring flowers native to the woodlands and hedgerows of Ireland, become available. These were replaced in September 2010 by a seventh series featuring animals and marine life using photographic images.
