Duh. ;)
A lot of Marvel series have recently reached the 600 issues mark. The geek in me has wanted to see something special done for issues numbered 616, because that's the numerical designation for the mainstream Marvel Universe.
Like I said, I'm a geek.
Sadly, no one has done it. Not Hulk, not Thor...
But now I have Captain America #616.
And it's his 70th Anniversary issue.
And it's HUGE.
I am satisfied.
