While tax status (W - 2 v. 1099) per se is not that important (
my wife works promotions and routinely gets half a dozen of each, or more, every year), the employee v. independent contractor status that they represent can be relevant.
Coincidentally, I just took on my first manga book
promotion project: the
work of Jim Balent and his
wife, Holly Golightly, of Jim Balent's Studio.
