Partly redrawn: Page 2 panel 1; page 4 panel 3; page 5 panels 2 and 3; page 10 panels 5 and possibly 2 (Ka-Zar redrawn by uncredited artists). The Ka-Zar face in page 2 panel 1 is possibly by Barry Smith (who pencilled the Ka-Zar story in Astonishing Tales #3) but the Ka-Zar figures in page 4 panel 3 and page 5 panels 2 and 3 are by a different artist again, possibly Marie Severin.
Possible Palmer coloring per information in Marvelmania # 2.
