50 Gulden Zonnebloem

Ootje Oxenaar's redesign of Dutch banknotes from the 1960s onward was a deliberate break from the solemn portraiture tradition — the Nederlandsche Bank gave him unusual creative latitude, and the results divided opinion sharply. The "Zonnebloem" (sunflower) series pushed chromatic intensity further than most central banks would tolerate, and the 50 Gulden is perhaps the most vivid expression of that approach.

Oxenaar also held an engraver credit here alongside J.J. Kruit, which was rare — designers rarely carried technical intaglio responsibility on the same note.
