This commemorative 20 Pfennig stamp was issued by the Deutsche Demokratische Republik (DDR) in 1978 to celebrate the 100th anniversary of the Leipzig Zoo. It features a beautifully detailed illustration of a leopard cub (Panthera pardus), symbolizing the zoo’s dedication to wildlife preservation. The stamp belongs to a thematic series highlighting notable animals of the zoo and is a popular choice among collectors interested in zoological and wildlife issues. Its clean design and naturalistic artwork make it an appealing representation of East German philatelic artistry of the late 20th century.
