1 Pound Isle of Man Banking Company

The Isle of Man Banking Company Limited was the island's oldest joint-stock bank, founded in 1865, and by the time this series entered circulation the company had already survived several regional financial scares that wiped out smaller Manx competitors. Johnston's Edinburgh press was a natural choice — the firm had deep experience with provincial and colonial bank paper across the British Isles, though their work for Manx institutions tends to be overshadowed in the literature by their map and atlas output.

The 1914–1926 date range spans the entirety of World War One, a period during which Isle of Man notes circulated under unusual pressure — the internment camps on the island held tens of thousands of civilian prisoners, creating an anomalous local economy largely invisible to mainland monetary records.
