The Provincial Bank of Ireland, established in London in 1825 and operating as a member bank of Allied Irish Banks Ltd, issued this note during a period of banking consolidation in Northern Ireland. The reverse design commemorates The Spanish Armada, a pivotal moment in British and Irish maritime history, reflecting the cultural and historical significance that Irish banks incorporated into their currency design during the late 20th century.

The obverse features a three-quarter profile portrait of a distinguished elderly man positioned on the right side, rendered in fine engraving with careful attention to facial features and formal attire. The portrait is framed by ornate decorative patterns including geometric designs and a circular Provincial Bank of Ireland emblem in the top left. Six heraldic shields representing Irish coats of arms are arranged in a row at the bottom center, symbolizing provincial heritage. The reverse showcases a meticulously engraved naval battle scene depicting The Spanish Armada with multiple sailing vessels engaged in combat on turbulent seas, occupying the central composition. Celtic-inspired knotwork patterns and stylized wave designs frame the central image, while ornate circular emblems containing the denomination appear on both left and right margins. The color scheme employs beige, tan, gray, and black on the obverse with darker blue tones enhancing the maritime scene on the reverse.
