This cover from France features 2 stamps of the same type, celebrating the
Lascaux Cave. Lascaux cave, in Montignac, was discovered in 1940. It is filled with around 600 polychrome paintings from about 17,000 years ago. It was opened to the public in 1948, but closed again in 1963 when it became clear that the paintings were being damaged by fungus and lichen growth caused by the changes in atmosphere brought along by the thousands of visitors. Exact reproductions can be visited since 1983 (Lascaux II, covering the two main chambers) and in 2016 Lascaux IV was opened, showing nearly all the paintings. Lascaux cave is a part of
Prehistoric Sites and Decorated Caves of the Vézère Valley, a UNESCO World Heritage Site in France since 1979.
