I don't know in what format people read them overseas but in France I was subscribed to two things :
"Le journal de Mickey" (Mickey's newspaper) Which was a weekly 30-35 pages book with two Disney comics and some articles.
"Mickey Parade Géant" (don't know a good translation sorry) which was a monthly ~200 pages pocket-sized Book aimed more at 15+ children, it had the best stories imo with reccuring ones.
Both of these contained a lot of translated comics from Italy, Spain, etc...
But Mickey Parade Géant always had a page before a story which indicated where it was from and a couple of facts about it's authors, sometimes even small interviews !
These stories remind me of all the multiverse stuff going on in movies nowadays, because each time it was the same characters (Mickey, Donald, Goofy...) With (often) the same personalities but in different roles and times !
I remember one where they were all superheroes (Ultra heroes I think), another where Mickey was a reporter in a big city, or one where he was a doctor ( and a bit unfriendly) in a parody of Dr House.
I should re-read them all in the correct order someday !
In germany as well, mainly in "Lustiges Taschenbuch" which still exists (new issues being released, still mainly translated from italian i believe).
When my family moved to the US when i was 10, i was shocked that no equivalent existed! And hugely disappointed by the US comic book culture because, although 10 year old me really liked the images, it felt impossible to know what was going on without access to all the volumes.
… and from Denmark. Those pocket books were huge in my childhood in the 80s and findable in multiple european countries so I was surprises to learn later that they weren’t really a thing in the Duck’s origin country.
