Ah interesting, for me it look like Oda have many plans for the cover, in the end he choose the beast pirates cover, was nice how he build up that cover. First King and Queen where above next to Kaido, but he change it and put the calamity under Kaido. In the middle it wasn´t first King but Jack, but he change his mind and put King in the middle? Nice to see that Oda have multiple thoughs about a chapter cover.
