This issue has variants.
Per Nick Caputo: "Spider-Man figure is by Kirby, probably inked by Brodsky. I spoke to John Romita and he recalls being in the office when Kirby was correcting the cover. It was changed because Spider-Man's rear was facing the reader". An unaltered version of the cover was published in an Italian reprint, L'Uomo Ragno # 29. (information updated December 16,2010).
