Issued in 1971, this 20-cent commemorative from the Netherlands Antilles celebrates the 40th anniversary (1931–1971) of the St. Theresia Parish in St. Nicolaas, Aruba. The design features a clean architectural rendering of the parish church, complete with its tall tower and red-roofed details against a deep blue background. Elegant typography surrounds the illustration, emphasizing both the commemorative dates and the island location. A fine thematic issue for collectors of Caribbean postal history, church architecture, and Netherlands Antilles commemoratives.
