I have the edition this picture is from in my shelf, my father handed it down to me when I was a kid. It’s a gorgeous edition, each part of the story is printed in a different color to represent which world it’s taking place in, I wish more books tried to experiment with the style a little bit. By the way, both links in your post lead to two different Spanish editions, mine is the one from the second link.
No problem! :) I think the original German version is extremely similar, even the font is the same haha.
