Why have the caves at lascaux been closed to the public since 1963?

The caves at Lasacaux have been closed to the public since 1963 because of the air was let into them and the   Humidity resulted in the rapid deterioration of the paintings.

By 1955, carbon dioxide, heat, humidity, and other contaminants produced by 1,200 visitors per day had visibly damaged the paintings.

tbh, either pop or, i know it's not on the list, but indie/ alternative.

first you need to pick out the favorite to the less favorite and have your pictures in a protector clear plastic then place your pics in the binder
