Back of Book

  • The back of the books shows signs of wear. It's spine has come unglued from the binded pages.
  • Despite the separation, the book binding itself is in excellent condition. The separation of the cover from the binding shows us the intricate detail of the hand stitched pages.
  • There is a pencil mark written inside the back page of the book that reads, "5000-", possibly signifying this book was for sale or purchased at least once before. We are not able to conclude which currency the dash (-) could be referencing.
