Marvel Two-In-One King Size Annual #2 comic book from Marvel Comics Group
This was one of the best comics I read as a kid.  There were so many heroes, all pitted in a life and death struggle with Thanos.  I still remember how out of place Spiderman felt with such heavy weights as Thor, Captain Marvel and even Moondragon.  But Spidey can hold his own with most characters in the Marvel Universe.
