On 9th October 1999, India Post issued this series of commemorative postage stamps to celebrate the 125th anniversary of the Universal Postal Union (UPU). This was part of a series that showcased various traditional art forms from different regions of India.

The first stamp reflects the cultural richness of the Rathva tribe. The Rathva Adivasi community, primarily located in Gujarat, is known for its ritualistic artworks, depicting scenes from daily life, mythology, and nature.

The second stamp offers a detailed depiction of a Muria fertility ring, which includes motifs of farmers, bullocks, fields, and harvest scenes. The Muria tribe, from Bastar in Madhya Pradesh, is known for their intricate metal crafts, including ritualistic objects such as fertility rings.

The third stamp from the left features Chhau masks. Chhau dance is a traditional dance form from West Bengal and Bihar, known for its elaborate masks and dramatic storytelling. The dance symbolises the victory of good over evil and integrates elements of mythology, religion, and folklore.

The stamp to the right, the Angami Ornament stamp, was the fourth stamp issued by India Post. The Angami tribe is known for its distinctive and elaborate jewellery made from natural materials such as conch shells, beads, and glass. The stamp features traditional ceremonial jewellery of the Angami tribe from Nagaland, including a conch shell necklace and beads.
