The title of issue #20 pretty much sums up the wild ride of 1970s comics: “Dinosaurs on Broadway!”
Spider-Man, at the behest of Curt “The Lizard” Connors, goes to the Savage Land to find a missing scientist who happens to be named Dr. Stegron and who turns into a Stegasaurus man, just like Connors turns into a lizard-man.
Ka-Zar talks a bit like a caveman in this story.
In the second half, Stegron and some of his dinos go to New York, where Spider-Man teams up with Black Panther to defeat the threat.
An exceptionally silly pair of issues, but harmlessly fun.
Creators: Len Wein, Gil Kane (#19), Sal Buscema (#20)
