This is an explanation book for Star Trek: The Original Series and The Next Generation. I purchased it new and have kept it in a bookshelf with a door. Non-smoking, no pets, no sun damage, no tears, and no stains. I think some discoloration of the paper due to aging is unavoidable. As the number of copies issued was small, it is rare to have volumes 1, 2, and 3 in this condition. 1) Star Trek Great Study (The Original Series) 192 pages total, 4th printing, August 1996, hardcover, 3,500 yen 2) Star Trek Great Study 2 (The Original Series) 264 pages total (excluding index), 1st printing, August 1996, softcover, 2,400 yen 3) Star Trek Great Study 3: The Next Generation Complete Guidebook 429 pages total (excluding index), 1st printing, August 1996 Includes information on the movie Generations, softcover, 3,000 yen 4) Star Trek Encyclopedia (English book) 396 pages total, a "Star Trek dictionary" with characters, spaceships, equipment, etc. from DS9 and Enterprise D listed in alphabetical order. I think even those who are not good at English can enjoy it. Purchased at a bookstore in Hollywood, US, for 28 dollars (approximately 3,640 yen) The condition of the books is very good. For Star Trek fans, or those who have recently become hooked on the new series, please take this opportunity. Because they are thick books, they will be shipped in a cardboard box with the recipient paying for shipping. (Around 1,000 yen within Honshu) Thank you very much. Note: I have checked the condition of the items thoroughly and am listing them with sincerity. If any damage occurs during shipping, such as damage to the product upon arrival, it will be covered by the shipping company's warranty. Therefore, we do not accept returns or refunds. We appreciate your understanding in order to prevent the "Mercari return fraud" that has become a problem recently.
