I'm afraid I have no answer to your question either, tn, but that museum looks fantastic, Steve - once I found the button for English

and was able to search the entire site. This was uncanny, because I just saw a documentary on Heinrich Wendel's photography of all the cave drawings not more than 6 weeks ago, and I saw there is an entire collection of his in the museum. How neat it would be to take kids there, and adults too of course, and do the workshops! There is nothing that can beat the hands on approach to learning, in my opinion.
