This is a pretty good interview; they sat down with him sometime after he got the Nomination for the National book award.  He talks about what got him into comics in the first place, and what he used to read (Marvel no less). I, Personally, like to know which side of the DC v Marvel  debate published comic authors are on, should they choose a side.  He also talks about whether he uses this as a catharsis for some own personal issues he may have had with his ethnicity.  He also pays homage to works like Maus and Love & Rockets for opening up readers’ and critics’ minds for works of this nature.
