Star Wars: Darth Vader Doctor Aphra Halloween ComicFest 2016 #1

Halloween ComicFest is a similar event to Free Comic Book Day.  Started in 2012, the idea is to attract customers to stores near Halloween by enticing them with free holiday themed comics.  Some of the comics are small-sized and sold in packs of 25 for giving out on Halloween.  Others are full-sized, like an offering from Marvel Comics on October 29, 2016, Darth Vader Doctor Aphra #1.  This comic reprints Star Wars: Darth Vader #3 and is timed to promote the new Doctor Aphra ongoing series that is coming out.
