Antarctic Ascidiacea was printed in 1969. The hardcover book has very little visible shelf wear on it. The pages are in great shape with no tears or stains. The countless pictures and diagrams related to a certain type of Antarctic aquatic life show absolutely no signs of sun damage or fading. The book tells you all about some of the first research sessions related to a exotic type of aquatic life inhabiting the harsh terrain of Antarctica and how they thrive there based on their experimentation. Great read! What you see is what you get. If you have any questions feel free to ask me anything about the book.
