KO #1 (October 1945)
I apologize for using an unrestored image for the cover of KO #1. The art for the cover is so poor I am unwilling to spend the time to restore it. Add to that the fact that the cover was not actually done by Jack Kirby. The most obvious sign that this was not done by Jack are the lower legs and ankles, particularly his left one. The outline is so sinuous that the form is broken. Jack was not accurate in his anatomy but he would not damage the structure like this artist has. Another feature not seen in works by Jack is the stiff arm swing, it is just too awkward. One final point although perhaps it is not as convincing as the other evidence. Jack had done only two covers using an oversized figure, at this point in his career Jack had stopped using that device.
