In reply to toad:
Mr Olsen says
"Now, however, I feel the moment has come to offer the rest of the world a chance to own and appreciate this remarkable work, which is the only version of The Scream not in the collection of a Norwegian museum"
So, why not give it to the museum where the rest of the world can see it, rather than it disappear into another rich persons private collection?
I prefer Munch's sunrise - dominating it's own room in the Munch museum.
