The earliest interracial kiss in a comic from a major publisher that I?ve found was in 1943, when Blackhawk kissed a Chinese woman:
It?s not quite what it looks like, though ? the woman gets her dying wish, a kiss from Blackhawk.
There?s a strong hint of interracial romance in a 1952 comic book of King Solomon?s Mines, though there?s no interracial kiss. On the cover, a white man and a black man appear to be fighting for the love of a black woman.
Yes, she?s lighter-skinned than the black man, but she?s still black in a time when interracial marriage was illegal in many states. As Gallup notes, only 4% of Americans approved of marriage between blacks and whites in 1958, while 77% approved by 2007:
DC Comics missed a chance for an apparent interracial kiss in 1970 when Lois Lane became black for a day:
To give DC a little credit, the writer had Lois ask Superman if he could love her if she was black:
He responded with a variant of the standard superhero cop-out, saying it would be too dangerous for him to marry anyone.
The first straight-up romantic kiss in comics didn?t come until 1975, in a Killraven story in Marvel?s Amazing Adventure #31:
But the first interracial kiss involving superheroes came in 1977, when Iron Fist and Misty Knight finally snogged.
