But that's really not unusual. On classic car- and spare parts-markets, you find masses of them, often formerly complete collections. From Haynes, also from the French "Revue Technique Automobile", the German "Jetzt helfe ich mir selbst" and the blue manuals from the Swiss publisher Bucheli. Plus uncountable masses of all kind of automotive magazines, original instruction manuals and so on.

In fact old manuals and magazines belong to the most collected automobilia-items.
