Tailte Éireann Commemorative Stamp

Commemorative stamp, first day cover, and cancellation for An Post marking the bicentennial of the first Ordnance Survey of Ireland. The stamp design is based on high-resolution scans from the archives of Tailte Éireann, the government agency responsible for mapping, surveying, and registering property in Ireland. The cancellation depicts a 19th-century surveying device called a graphometer.
