This classic Netherlands definitive features a left-facing profile of Queen Wilhelmina, rendered in a refined engraved style and printed in deep green. Issued during the mid-20th century, this long-running series is a foundational element of Dutch postal history and a favorite among definitive-series specialists. The clean portrait and crisp “NEDERLAND” typography make it an excellent representative example of the era’s understated design. A solid addition for collectors of monarch portraits, European definitives, or Netherlands classics.
