This video features all ads from the Feb 1980 issue of Iron Man from Marvel Comics, circulated in late 1979. Period music accompanies the video. Watch once in its entirety, then if you wish, watch again, pausing to catch some interesting details. (For example, the Mego ad instructs, "NJ residents add 5% sales tax". It is 7% at the time of the video's creation.
