The spine has been reinforced with red vinyl tape and the boards' corners chipped; the front hinge, which is cracked, has been reinforced with both white vinyl tape and two small strips of adhesive bandage, as has the back hinge, but without the red vinyl, which is used again on the hinge behind the front end paper. The book is foxed and there is a pencil ownership inscription on the front end paper, and what I think must be a school book review, also in pencil, on the verso of the title page, written in "Berlin, 27 Mai 1930". Apart from these hideous repairs, I'm innocent, the body of the book is in excellent condition and the binding tight.
