Submit your artwork in one of two fashions:
1) as artwork only, allowing Phoenix staff the discretion to design it into a cover
2) as a complete cover concept with front and back covers, spine and relevant typography.
The theme for the 2019 Phoenix Cover is not yet determined. It will most likely be announced in October of 2018. However, the cover does not necessarily have to adhere to a theme. You may submit anything you think would work well as a cover.
