German text book (Keresley Newlands CV7)

I f anyone is home schooling or wants to learn German, this old, much used teach yourself book is in poor condition but still clearly readable and can still be used effectively. Because the spine binding is coming apart it needs to be treated carefully, placed on a desk to read rather than casually open on one's lap. The spine can probably be gummed by someone with experience. There's some foxing and a small cut on one page but, that doesn't interfere with its legibility and it would be a shame to condemn it to landfill while it can still be of use.
