Issued by the Central Bank of Ireland on April 21, 1975, this note represents Ireland's post-independence monetary identity, incorporating bilingual English-Irish inscriptions and Celtic design elements reflecting the nation's cultural heritage. The classical male portrait on the reverse and the female profile on the obverse are characteristic of Irish currency design during this period, emphasizing historical and cultural symbolism during a time of economic development in the 1970s.
The obverse features a woman's profile portrait in classical style, facing left within an oval engraved frame, positioned on the left side of the note. The reverse displays a classical bearded male portrait head (likely representing a historical or mythological Irish figure) in three-quarter view, centered within elaborate architectural framing. Both sides are framed by ornate Celtic knot patterns and decorative scrollwork characteristic of Irish cultural design. The denomination £1 appears in decorative format in the corners of the obverse. The bilingual layout reflects post-independence Irish currency standards, with English and Irish (Gaelic) text given equal prominence throughout.

This note is cataloged as Pick P-64c, the security thread variant. The PMG population report identifies four variants for this base Pick number: P-64a, P-64b, P-64c (with security thread - this specimen), and P-64d, all with the 'Head of Erin' watermark except P-64c which features the security thread as the distinguishing characteristic. The observed serial number 87K755008 with the 'K' prefix is consistent with the 1975 issuance. The date 21·4·75 (April 21, 1975) marks this as an early issuance from the first day of circulation.
