Issued in 1975, these United Nations stamps commemorate the International Women’s Year, a milestone promoting gender equality and women’s empowerment worldwide. The design features symbolic male and female figures joined by an equality sign within a laurel wreath — the emblem of the UN. The contrasting color schemes of blue (10¢) and green (18¢) underscore the universal message of parity across all nations. These stamps mark the beginning of the UN Decade for Women (1976–1985), a cornerstone in global human rights philately.
