It's important to remember that there are many independent and smaller comic publishers out there, and some may have created a comic book series titled "Southpaw." If you have any more information about the comic book, like the publisher or the creator, I might be able to help you find more information.
Could you please provide more context about the comic book you are referring to? For example:
* Publisher: Do you know who published the comic?
* Creator: Do you know the name of the artist or writer?
* Specific issues: Do you remember any specific issue numbers or story titles?
* Genre: What kind of comic book was it (superhero, horror, etc.)?
With more information, I can assist you in finding when the comic was created.
