Analysis of information sources in references of the Wikipedia article "Iron Man (comic book)" in English language version.
To celebrate the #500 issue, the numbering started with Iron Man (I) #1 is resumed with the issue dated March 2011. (Although I count 332 issues of Iron Man (I), 13 issues of Iron Man (II), 89 issues of Iron Man (III), 35 issues of Iron Man (IV) and 33 issues of The Invincible Iron Man (V) - which sums up to 502 issues already - from the cover gallery in #500 it seems that Marvel does not count Iron Man (IV) #33-35 and then it makes 499.)
