Tonga Tin Can Mail, Self-Adhesive Stamp

Tonga · 1983 · 45s (seniti)

This unique, banana-shaped stamp commemorates the famous 'Tin Can Mail' of Niuafoʻou island. The design depicts a swimmer carrying mail sealed in a tin can from a waiting ship to the shore, a method used due to the island's lack of a safe harbor. It is notable for being one of the world's first self-adhesive postage stamps.

The Tin Can Mail operated from the late 19th century until 1983, providing a vital link for the remote volcanic island of Niuafoʻou. This stamp marks the end of that unique postal tradition.
