1 Pound Ulster Bank

Ulster Bank Limited was a Belfast-headquartered commercial bank operating under a note-issuing privilege that persisted long after the partition of Ireland — one of the handful of authorised private issuers still circulating sterling-denominated notes in Northern Ireland under the Currency and Bank Notes Act 1928. Bradbury Wilkinson, working from their New Malden facility in Surrey, produced notes for numerous colonial and Commonwealth issuers throughout the postwar decades, and their intaglio work for Ulster Bank maintains the restrained, formal quality consistent with their British commercial banking commissions of the period.

The watermark remains the sole listed security feature, modest even by 1966 standards, when other issuers were beginning to incorporate threads.
