I read a few Japanese comic book anthology magazines that contain an anthology of several manga by various creators. The paper quality was newsprint and the format/size of the anthology magazine was as big as that of a US comic book. I read not only some shounen anthologies such as Weekly Shōnen Jump but also seinen anthologies such as
Weekly Young Jump. (seinen is for adult men while shounen is for young boys).
In a seinen manga anthology magazine called
Young Champion, I saw not only various manga series but also pinups of pretty attractive women, sometimes scantily clad, occasionally nude). I bought and owned a couple of seinen magazines.

I was thinking, Maybe the US comic book publishers should try to insert pinups of semi-nude or nude women in their comic books to attract sales. The majority of comic book fanbase are grown-up adult men, so it should be fine, right? They can also slap a rating system on the comic books to prevent minors from buying the comic books.
Playboy magazine, a magazine that prints articles devoted to men's interests, also printed pinups of nude women.
