50 Gulden 'Helmeted Minerva'

Jacques Jongert was an unusual choice for a banknote commission — he came primarily from poster and applied arts work, not the engraving tradition that dominated Dutch note design. The Helmeted Minerva series reflects that background: the composition is flatter and more graphically assertive than contemporaneous Enschedé output, closer in spirit to Dutch constructivist commercial printing than to classical intaglio banknote convention.

The series ran across a tight three-year window, 1929–1931, bracketing the onset of the Depression. Replacement demand stayed low; the Netherlands held to the gold standard through 1936, which kept monetary conditions contractionary and note turnover slow.
