I'm in the process of creating some promo pieces (5x5 square prints) to send to galleries and came across this dilemma. Most of my prints are in editions of 30. There are several images that I would like to use in these promo pieces, but was wondering what the protocol on doing so is? Do these smaller prints count towards the numbered editions or does that only apply to likely sized prints (my numbered editions are 17x17")? Am I violating some unwritten rule by printing these promo pieces?
