This is S.M.H. No. 12, published in September 1998. I purchased it at a bookstore when it was first published. I've looked through it many times since then, and especially during my student days, I carried it around and used it as a reference for classes and assignments, so the condition is as you can see, not great. The cover has discoloration from sun damage on the left side, as well as wrinkles and scratches. The pages inside are relatively clean, but there are still some wrinkles. Please understand that this is a used, second-hand book. Shipping is planned via Rakuraku Mercari Bin (a Japanese delivery service).
