Although these stamps are from 1989, the reticulated giraffe was only officially recognized as a species by the IUCN (International Union for Conservation of Nature) in 2025.  Until then, giraffes were classed as one species with nine subspecies.  Distinctive features are the sharp white lines that define the reddish-orange patches that extend down their legs and across their faces.

These creatures can reach up to 6 meters tall, making them the tallest land animal.  They mostly live in Kenya and were considered endangered in 2018, but are slowly recovering with a population of around 16,000-20,000.
