Mysterious Sculpture Left at Library

I interrupt this log of books I'm reading for review to add a little whimsy.  Someone in one of my online art groups included a link to a blog which tells of a mysterious sculpture left in an Edinburgh library.  Great stuff!  As someone who makes miniatures as well as reviews books and has a library degree, I now have something to aspire to doing.  I think every library should have mysterious sculpture left in it!
