This is the one where JJJ creates a spider-slayer prototype, plasters a video feed of his face on the front, and goes after Spidey. First appearance of Spencer Smythe.

The first appearance of Mary Jane Watson!
Steve Ditko gets a “plot” credit—pretty cool—but Stan still takes script. Ditko’s on pencils and inks, as usual. This “credit” note, below, reflects the increasing, ongoing tension between Steve and Stan, where Steve felt Stan was a credit-stealing blowhard and Stan felt nobody would even know who Steve Ditko was if Stan wasn’t such a masterful writer and hype man. Probably a lot of truth on both sides of the equation, really.
First appearance: Mary Jane Watson, sort of, because her face is obscure. But at least we know she exists—before now, she’s just been a character Aunt May uses to threaten Peter’s social life.
