Issued by East Germany (DDR) in 1988, this commemorative 85-pfennig stamp honors the 40th anniversary of the World Health Organization (WHO). The design features the WHO emblem, with the Rod of Asclepius placed over a global map encircled by olive branches, symbolizing health and peace. Above it appears the DDR state emblem alongside the inscription “40 Jahre WHO”. A fine example of Cold War–era philately, this issue highlights DDR’s recognition of international health cooperation. A must-have for collectors of thematic stamps on medicine, international organizations, and German postal history.
