The National Bank of Vietnam was established only in 1951, giving it barely two years of institutional existence before this note was printed. De La Rue's involvement reflected a broader pattern of newly independent or quasi-independent states contracting established European security printers while domestic infrastructure lagged — the Associated State of Vietnam under Bảo Đại was nominally sovereign but still deeply embedded in French financial arrangements when this series was commissioned.
