The Banco Nacional Ultramarino was Portugal's primary instrument for managing currency across its overseas territories, and this 20 Escudos note was issued for circulation in Portuguese Guinea — one of several African colonies where the BNU held exclusive note-issuing authority under concession from Lisbon. The seven distinct signature combinations on Pick 26 indicate an unusually long active life for a single design type, with Francisco José Vieira Machado appearing as a constant across all pairings, suggesting his tenure as a senior signatory anchored the series through multiple administrative changes.
Bradbury Wilkinson's New Malden facility was at this point producing colonial currency for several European powers simultaneously.
