Most people mark the beginning of this period with the introduction of Silver Age Flash, but I start it a little earlier with the success of Strange Adventures. While the period was categorized by a resurgence in superhero comics, it’s important to note the heavy science fiction influence on almost every title of this era. That’s from legendary editor Julius Schwartz, who was a sci-fi superfan. This lighthearted era comes to a close around 1970, when the slightly darker Bronze Age begins.
