My grandmother's friend had a severely mentally handicapped son who she had to take care of until he passed away at ~40 years of age.  When he did, she gave me several boxes of comic books that belonged to him.  There were a lot of war comics from the late 50's and 60's - Fightin' Navy, Fightin' Army, SGT. Rock, SGT. Fury...
a lot of DC and Marvel comics - Superman, WonderWoman, IronMan, Spectre, Aquaman, Batman, Spider-man, Daredevil, Dr. Strange, Avengers, Thor, Fantastic Four, Hulk... oh and my favourite Green Lantern (though I'm not sure why).
I don't remember them all but I probably read them each several times and they were all very entertaining to me.  The prices on them ranged from 10 to 25 cents... wish I had taken better care of them - who knew comic books would have been worth so much to collectors.  I never bought many of my own - I had a hard time justifying spending so much on something I would be done with in less than 15 minutes and back then I made 3 cents per paper for delivering on weekdays, 15 cents for the Saturday paper (but it was a beast) and $1.85/hr bussing tables in a restaurant/buffet on weekends.  I never really got too deep into comic books after that but I picked up 12 in the series "Crisis on Infinite Earths" and stored them properly because a comic-collector friend of mine told me they would be worth something someday.  It radically altered DC, the artwork was pretty good and it was quite entertaining... since then, I haven't purchased a comic book though.  I guess you grow out of it.

 The one you just looked at was shit though (Ultimatum wasn't very well received and you might say it was reviled) but I needed to find the image of Dr. Strange being killed.  The old mainstays are still there so there are still some great comics available - I wouldn't want you to be put off just for that one I posted.
