This 2-rupiah stamp from Indonesia depicts a traditional Minangkabau-style house, characterized by its high, curved roof and stilted structure, symbolizing the rich cultural heritage of Sumatra. Originally part of a definitive series showing traditional Indonesian architecture, this stamp features a black overprint reading “RIAU”, denoting its regional reissue for the Riau province. Such overprints were used during administrative reorganizations and carry special interest for collectors focusing on Indonesian provincial issues or overprint varieties.
