There are certainly plenty of people in those comics, but a lot of them are anthropomorphic birds and anthropomorphic mammals.
I do remember a lot of people who looked similar to humans back when I read those comic books, but I don't remember closely inspecting them to see if they were drawn like comic book humans or like one or more species of anthropomorphic mammals.
So I ask if the majority of human-looking characters in Duckburg or Mouseton and in the wide world are humans or anthropomorphic mammals in the mickey Mouse and Donald Duck comic books.
