Sorry, too fast so here again:

1. Go to the website www.tropenmuseum.nl and make your choice in English (right) and then click on "collection on line"
2. Scroll on that page and you will see the text "also the Tradebeads from the Sick collection"
3. Click on the text again and voila: all the information is there!

And then I made it one of my favorites!

Enjoy it and have a nice day. Here in Holland we are now in winterwonderland!
