The High Museum of Art at Atlanta and Terra Foundation for American Art at Chicago was the American museum that used $6.9 million dollars.
The Neolithic Period art is more ancient styled. Number 1 it looks like it's covered in amber. Second of all, it is slightly different rock, and finally it is much older and ancient than the Upper Paleolithic Art, which is a bit brighter, little bit newer, and not super faded.
Brainliest please.
