1st Printing. Reprints Tales of Suspense 39 (origin and 1st appearance of Iron Man)
Jack Kirby layouts.
Identification Notes: 1st printing has a glossy silver cover and the 2nd printing has a darker grey and duller appearance; however, the easiest way to differentiate between the 1st and 2nd printing is to flip over to the back cover, if it has the 'Swinging Spider-Man' UPC on back cover, it is the 2nd printing from JC Penney.
Cover price $2.95.
