The Series B banknotes () of Ireland replaced the Series A banknotes. The banknotes were issued between 1976 and 1992 by the Central Bank of Ireland, the series was replaced in 1993 by Series C banknotes. Banknotes The Central Bank announced its intention for the new banknotes in December 1971 and Servicon, an Irish design company, was employed to design the notes of the denominations; £1, £5, £10, £20, £50 and £100. The £100 note was never issued or circulated; this remains somewhat of an idiosyncrasy in the issue of Irish banknotes as this is the only series without a note of this denomination. The series was Legal Tender from 1976–1995, although not printed after May 1993. The theme chosen for these notes was history of Ireland, and each note featured the portrait of a person with this theme in mind from a particular era from historic to modern and complementing visual elements. The portrait of Lady Lavery painted by Sir John Lavery was retained from Series A; contained as a watermark in the unprinted space. Each banknote has the signature of the Governor of the Central Bank of Ireland and the Secretary of the Department of Finance. During much of the period of circulation of this series, foreign exchange controls prohibited the export of any notes larger than £20 from the Republic. One Pound The one pound note has a portrait of Medb, the legendary Queen of Connacht in Irish mythology. Also a pre-Christian geometric design based on those found on bone slips is used in on the note, the background is an excerpt from the Táin. The reverse is a decorated excerpt from Lebor na hUidre, the oldest surviving Irish manuscript. The one pound note was removed from circulation from June 1990 as it was replaced by the Irish pound coin. It was the final one pound note to be circulated and the first note of Series B to be removed from circulation. Five Pounds The five pound note has a portrait of Johannes Scotus Eriugena, the philosopher and theologian, of the ninth century. The letter A from the start of Psalm 17 of the Psalter of Ricemarcus is used against the Book of Durrow. The reverse features an adaptation of animal and script extracts from the Book of Kells, an eighth century copy of the gospels. Ten Pounds The ten pound has a portrait of Dean Jonathan
