‘Marvel Comics’ #1
Most of Marvel’s big contributions to the comic book world came after World War II, so they’re not quite as rare as Golden Age books starring Batman and Superman. One exception to this is “Marvel Comics” #1, which features the original Human Torch (no relation to the Fantastic Four character). A copy of this comic sold in 2014 for $3.2 million, making it the most expensive comic ever purchased at that time.
