I don't really have anything to add, I just love this book. I searched for "The NeverEnding Story" in this community, saw that there was no post about it and wanted to fix that :).
Image found on Facebook. I think the source of that specific printing is the Spanish version of the book, [EDIT: as pointed by @alvarolh@lemm.ee, the version on the link is also a Spanish version, I may have had a brainfart because of the font (?)] ~~but it's very similar to some German version covers~~.
No problem! :) I think the original German version is extremely similar, even the font is the same haha.
