The division between penciller and inker described here is most frequently found where the penciler and inker are hired independently of each other by the publisher. Where an artist instead hires his own assistants, the roles are less structured; an artist might, for example, ink all the faces of the characters while leaving the assistant to ink in the backgrounds, or work with the inker in a more collaborative fashion. Neal Adams' Crusty Bunkers worked like this, with say one inker responsible for the characters' heads, another doing bodies, and a third embellishing backgrounds. The inking duo Akin & Garvey had a similar arrangement, with one inking the figures and the other the backgrounds.
