First, let’s take a look at the cover, crafted by Alex Ross, in its entirety.
Then, if we zoom in to the area where Spider-Man appears in the bottom-left corner, as spotted by CBR, and look closely just below the web-slinging hero’s right leg, we see Superman’s boot.
This is actually an homage to the cover of Superman vs. The Amazing Spider-Man: The Battle of the Century crossover comic, which released back in 1976 and was designed by Carmine Infantino and Ross Andru.
What might this mean for the upcoming Marvel Comics‘ graphic novel? We’ll just have to wait until Secret Wars #8’s November release to find out.
