Generally speaking, comic book covers should never be taken literally; the action they depict is often far removed from what actually happens during the story within. But aside from the minister's truly deplorable pun, which he sadly does not utter during the story proper, this cover hews fairly closely to the story: Aunt May is indeed happy about marrying Doctor Octopus, and yes, the wedding guests are mostly gun-toting hoodlums. Poor innocent Aunt May, always determined to see only the best in everyone...except, of course, "that dreadful Spider-Man!" - her own nephew! Ah, dramatic irony.
