Thank you for viewing. - They went extinct for a reason. The "Unfortunate Creatures Encyclopedia" is interesting! The mysteries of evolution. - The Unfortunate Creatures Encyclopedia - The Sequel to the Unfortunate Creatures Encyclopedia - The Second Sequel to the Unfortunate Creatures Encyclopedia This is a set of 4 books. The covers have some creasing and scratches. The inside is in relatively good condition. Please forgive any oversights. Please consider purchasing if you understand that these are used items. If you are looking for a pristine item or are very particular, please refrain from purchasing. I also have many other picture books for sale, so I would be happy if you would take a look.
