Thanks to Brian S. for the heads up
It has been announced that Ghost Rider may be on Marvel’s Agents of SHIELD, just not the one you think.
According to Comicbook.com, the characters they are casting are two Latino brothers. That means it will not be Johnny Blaze or any of the older Ghost Riders, but the more recent Robbie Reyes.
Robbie and his brother first appear in All New Ghost Rider 1. Copies have been flying off eBay fairly quick as this is a cheap TV spec book.
Mycomicshop.com still has copies for around cover price.
There are several variants for the comic, including a horrible Hamster one, a Skottie Young, and also the Frank Kozik Labbits Hasting variant (which I was lucky enough to score dirt cheap at the Hastings Clearance.)
