10 Gulden Frans Hals

Oxenaar's first commission for De Nederlandsche Bank, and the note that established his reputation as the most consequential banknote designer the Netherlands produced in the twentieth century. He broke decisively with the engraved portraiture tradition, using loose graphic line-work and a deliberately unmonumental treatment — a choice that drew considerable internal resistance before approval.

The series ran until 1990, an unusually long active life for a Dutch note of this period. Enschedé printed the entire run from their Haarlem facility, a few hundred metres from the Frans Hals Museum itself.
