Winnetou Vol. 1, 2 & 3 by Karl May 

Hard cover set 

Circa 1962 (I do not see a date, but I have seen other sets with the same cover with 1962 as the date).

The text is entirely in German.

The books are in overall very nice condition. All three books had a name stamped on the first page and the back end page which was blacked out with a marker. The pages are clean and unmarked.
