This 1972 United Nations First Day Cover features a block of four 8¢ Human Environment stamps, postmarked June 5, 1972, at United Nations, New York. The attractive cachet depicts a golden globe encircled by books beneath the words FIRST DAY COVER.
The issue marks the United Nations Conference on the Human Environment, held in Stockholm later that month—the first major global forum dedicated to environmental protection and sustainable development.
A notable detail is the large, clear first-day cancel that ties the stamps while preserving the striking red, white, and blue design showing a stylized human figure within a laurel wreath.
This cover makes an excellent addition to any United Nations or environmental-topical collection, with fresh colors and a well-struck postmark.
