Otago Museum Bulletins 1 - 6, published between 1967 and 1988. Part 1 has dull paper cover, the other parts in glossy (or near glossy) covers. Pt 2 is hard cover, the others with card covers. All volumes are in very nice condition. They are ex museum copies but have minimal library markings and little wear. A nice set. These are a heavy set so please check postage with bookseller.
