Issue: Amazing Adventures #31 (1975)
Why it’s significant: It’s the first interracial kiss in mainstream comics.

Comics were taking baby steps to become more diverse during the ‘60s and ‘70s, and one of the most notable examples of one of these small victories is when M'Shulla and Carmilla Frost kissed in Amazing Adventures #31. It might not seem important on the surface — especially because, well, who cares about M'Shulla and Carmilla Frost? — but this seemingly insignificant moment was actually the first interracial kiss ever in a high-profile superhero comic. We’ve seen plenty of interracial relationships since then, but this one panel opened the door for all of them. Sometimes the biggest barriers are broken in the smallest books.
