Please add cover to edition (Done)

Hello,

this edition https://www.goodreads.com/book/show/9... still needs a cover.

Here is a link to it: https://www.jugendliteratur.org/buch/...

Source is the website of the German organization for childrens' and adolescent literature.

That doesn't look like an acceptable source.
