This is an example of a vertical Page Illustration.
Horizontal Page Illustrations would be displayed along the top or bottom of the page.
As we have no idea at this time how many pages there will be, we can't really say how many page illustrations we'll need. If you're interested in submitting multiple images, email us and we'll discuss it with you.
Priority will be given to an image by someone who has submitted nothing else over a multiple submission by another member.
