The Twenty Years' Crisis, 1919-1939: An Introduction to the Study of International Relations By Edward H. Carr There is creasing at the top of the cover. The edges and margins of the pages have a yellowed appearance (※). Also, likely due to the binding process, there is a single crease on both sides of one page (last two images). Other than the above, there are no visible markings or stains, and the book appears to be in unused condition. ※Regarding the yellowing, the images appear somewhat whiter than the actual book due to natural lighting. Please refrain from purchasing if you are concerned about minor imperfections.
