A couple of month ago I told you about a monster of a 50 year old palm frond we had just acquired. Plans are to put the frond on display at World Museum Liverpool but first it needed some TLC in the form of treatment at the National Conservation Centre. This primarily involved removing the enhancing layer of acrylic paint to expose the original fossil (it's much paler).
This image shows the frond under UV light before work began. The purple areas are the acrylic overpainting and retouches. Images of the conservation work in progress and the finished article can be found on our Flickr page.
Update 23.01.07: apologies, that should have read 50 MILLION year old palm frond.
