 For example, Spider-Man's high school graduation was published in "Amazing Spider-Man" #28 (September 1965), his college graduation in "Amazing Spider-Man" #185 (October 1978), and his high school reunion in "Marvel Knights Spider-Man" #7 (December 2004).Because of the floating timeline, where stories refer to real-life historic events, these references are later ignored or rewritten to suit current sensibilities; for instance, the origin of Iron Man was changed in a 2004 storyline to refer to the War on Terror in Afghanistan, whereas the original Iron Man stories had referred to the Vietnam War in Vietnam; similarly, The Punisher's backstory has also been changed as well.Marvel Comics itself exists as a company within the Marvel Universe, and versions of people such as Stan Lee and Jack Kirby have appeared in some of the stories, whereas characters like Steve Rogers, (Captain America's alter ego), have worked for Marvel.
