This is the fantastic work of Berlin-based artist Alexander Korzer Robinson. The work is made by cutting through books to create assemblies of images in relief. Very skilled stuff.
The cut book art has been made by working through the books, page by page, cutting around some of the illustrations while removing others. The images seen in the finished work, are left standing in the place where they would appear in the complete book.  As a final step, the book is sealed around the cut, and can no longer be opened.
Using generally discarded materials, these books regain new purpose. They are no longer tools to learn about the world, but rather a mean to gain insight about oneself.
