Marvel Two-in-One #55

The cover of this September 1979 issue — penciled by Keith Pollard and inked by Joe Sinnott — pulls no punches: the rocky-hided Thing and a towering, black-and-gold-costumed Giant-Man grapple in a chaotic struggle while bystanders scramble in the background. The cover blurb announces "Nuklo Berserk at Project Pegasus," promising that the action-packed third chapter of "The Pegasus Project" escalates things considerably. With Ben Grimm and Giant-Man sharing the stage against whatever threat Nuklo represents, this mid-series installment looks like a true team-up done right.
