And let's not forget her boyfriend Comet.
These stories can be filed under forbidden romances I guess:
I Love Ya But You're Strange - Brian Cronin
Supergirl Made Out with Her Horse? - Comic Vine
Great copy, my friend. One of my favorite Actions. And love your comments about the cover, too.
Comet, definitely one of the more wacky and out-there silver age concepts. You think there would have been a more straightforward way to introduce a superhorse...but then it definitely wouldn't have been as fun in hindsight.
Anyways, here's my favorite Comet cover.
It's got it all...Comet, the fortress, a stern Supergirl, a bewildered Superman, sexist comments!!
