Book is in good shape with some wear, tanning to pages, damp stain on top edge, and a few spots of what appears to be fingernail polish to front cover. No markings. This vintage paperback book, titled "The Lost World" and written by Sir Arthur Conan Doyle with awesome dinosaur t-rex cover art, is a perfect addition to any collection of classics or vintage paperbacks. Published by PYRAMID in 1960, this book is a great find for collectors and fans of Conan Doyle's work. The book features softcover wraps and contains the original text in English.
