I have admired these drawings and they were labeled Milo in my download folder from the late 1990s. I liked the coloring and the clean lines of the drawings. He also did more complex drawing with fantasy themes.
From the Spanking Art Wiki a favorite site and source that I had thought gone, Manara’s style favors clean lines for women reserving more complex drawings for monsters or other supernatural elements. Like his compatriots Tinto Brass and Leone Frollo, he evidently has a fixation with the female buttocks. He is not alone there!
