We require at least 4 finished spreads of art work, and then pencil roughs of the whole story line, i.e the full 32 pages. The pencil roughs can be in the form of a dummy. They can be quite basic - it's just so we can see and read the story in its entirety.
I hope that's clearer. Give me a ring if you want to discuss it further (020 7014 6124)
