This commemorative stamp from São Tomé and Príncipe was issued in 1997 to honor the life and legacy of Princess Diana, Princess of Wales. The design features a striking photographic portrait of Diana wearing an elegant purple evening dress at a formal event, reflecting her global reputation for grace and humanitarian work. Released shortly after her tragic passing in 1997, the stamp became part of many international memorial philatelic issues dedicated to her memory. With its vivid color and contemporary photographic style, it is a notable item for collectors of royal-themed and modern commemorative stamps.
