Indonesia Riau Archipelago Overprints Complete Set

Indonesia · 1954 · Various

This is a complete set of 41 stamps issued for the Riau Archipelago, created by overprinting existing Indonesian definitive stamps with 'RIAU'. The set includes various designs from the 1949-1952 definitive series, featuring themes of Indonesian culture, industry, and agriculture. The overprints were a provisional measure for this specific postal territory.

These stamps were issued for use in the Riau Archipelago, a group of islands in Indonesia, following a period of dispute over their administrative and economic status. The overprints served as a temporary solution to provide valid postage for the region.
