Bizarro Back Issues: Green Arrow Plus Aqua (1959)
Last week, I wrote about "Manhunt on Land," an Aquaman story where he drove around in a pickup truck full of fish to track down a sea crook who had taken to land for the express purpose of avoiding being dragged back to jail by Aquaman. That in and of itself is a solid premise, but what really makes it interesting is that it was a strange little rarity of the Silver Age: It was actually a crossover with a Green Arrow story in the same issue.
Sadly, the second half doesn't have the immediate hook of a pickup truck that's also an aquarium, but it's definitely a story worth talking about --- not just because of the unusual crossover element, but because it has one of the most shocking endings I've ever read. And for the Silver Age, that's saying something.
