Ulster Bank will complete its current polymer series with the issuance of a £50 banknote on June 15, 2022.

The reverse of the banknote also portrays a "Millie" (female mill worker) working at the loom, as an homage to the unsung heroes of Northern Ireland's great linen industry. These women were seen as "unskilled operatives" at the time but have since been celebrated for their skilled work. There are also nods to the shipbuilding and aviation sectors, the creative industries and Northern Ireland's place as a center of excellence in cyber security.

The obverse of the banknote shows a range of flora and fauna found in Northern Ireland, including a pine martin, a cryptic wood butterfly and gorse, whose thorny spines make it a corridor and safe haven for wildlife.
