This is the comic that introduces “The Infinity Formula,” which is what explains why Nick Fury still looks younger than Captain America. After being mortally wounded during WWII, a French doctor gave him an experimental drug to save his life. Now, he must take the same shot every year to stay young.
It’s better than having a picture like Dorian Gray, right?
The story involves Nick needing the serum, but it’s been taken by a bad guy. Turns out, he’s getting extorted, every year, for his annual injection.
Of course, he prevails.
