That pretty much does it for the more interesting forms of horror, and as a result, the "horror" comics of the Silver Age were pretty tame fare, mostly featuring monsters like Frankenstein. By the end of the 1960s the cracks in the CCA wall were becoming obvious, and in the 1970s horror with vampires and all returned with a vengeance.
So here's a little quiz about some of the moderately horrific comics of the Silver Age:
1. In Detective #336, Batman was bewitched:
Who was the witch, and who was the real mastermind behind her?
2. Although vampires were prohibited, the CCA allowed two stories featuring a villain who stole the life force from people, battling (and battering) Superman. What was the name of this villain?
3. Who was the original Green Goblin?
4. What was the name of Marvel/Atlas' late 1950s ripoff of Casper, the Friendly Ghost?
5. Although werewolves were banned as noted above, one key DC character turned into a wolf in a mid-1960s comic. Name him.
