Thank you for viewing. This is "Political Science Structure" by Itsuo Sugiyama et al., published by Nansosha. It was a textbook during my university days. The cover has discoloration and deterioration, but the inside is clean except for one folded page. It is the 4th printing, published in 1984. The original price at the time was 3200 yen. Please refrain from purchasing if you are concerned as it is a used item. Instant purchase is OK. If you have any questions, please leave a comment.
