These are italian first editions, but the german ones you showed are different.
The italian books were structured this way: they used the story from a main title (i.e. Spider-Man) which also gave the name to the italian title, and then featured backup stories from another character, taken from additional US titles.
While I think these recent german adaptations try to mimic the original US book also in its editorial form, and thus they should be slim books with a single story featured (and are not, in general, the first edition in german of that title).

This has essentially been my view since I started collecting foreign books.
