*Reggae musician Ziggy Marley serves as co-writer of a new comic book series based on one of his biggest hobbies.

The son of legendary reggae icon Bob Marley will be working with Image Comics on Marijuanaman, which follows the adventures of an alien superhero who comes to Earth to protect the marijuana crops that his people desperately need to survive.

He’ll be signing posters for the series at San Diego’s Comic-Con International on Saturday July 24.

“I have been reading comics since I was a little boy in Jamaica,” said Marley. “I am very excited to be a part of Image Comics, Comic-Con and the comic book community.”

Marley is teaming with co-writer Joe Casey (Gødland) and artist Jim Mahfood (Mixed Tapes) for the series, which debuts – of course – on 4/20/2011.
