This cover from Portugal depicts 2 stamps of the same type (from a set of 4) celebrating Lisbon as the Ibero-American Capital of Culture in 2017. The stamp features a picture of
Machu Picchu, Peru, inscribed as a Cultural Heritage site since 1983,
Machu Picchustands 2,430 m above sea-level, in the middle of a tropical mountain forest, in an extraordinarily beautiful setting. It was probably the most amazing urban creation of the Inca Empire at its height; its giant walls, terraces and ramps seem as if they have been cut naturally in the continuous rock escarpments. The natural setting, on the eastern slopes of the Andes, encompasses the upper Amazon basin with its rich diversity of flora and fauna.
