This issue is a variant of Iron Man (Marvel, 1968 series) #258 [Direct]. There exist further variants.
Part of a boxed set of comics that could be ordered from JC Penney catalogs in 1992. In the UPC box it has an image of Spider-man and the text "30th Anniversary the Amazing Spider-Man 1962-1992".
[information taken from the STL Gallery and Roger Perez with permission from James Jobe]. Variant cover is a 1992 / 1993 J.C. Penney Marvel "Vintage Pack" reprint. All the issues in the J.C. Penney MVP set have common identifying characteristics. The most obvious is that all have a swinging Spider-Man in the UPC. There is also a blank under the issue number in the price box where the regular edition has the UK price. Secondly, the indicia clearly states Second Printing at the end. Lastly, they all have the same ads from 1992 and back cover which differ from the original printings. The back cover has an X-Men card ad with Wolverine bursting out of it.
Armor Wars II, Part One. "if you take the first letter of each word in the title (and in the
next issue), they spell LASER, which was Byrne's sneaky way of telling us who the villain was." (e-mail from Roger Ott, October 9, 2007).
