Yes. Authors in the Creative Partners Program join with Storybird to commission exclusive artwork from Storybird artists and/or outside talent; the financial arrangements are specific to each project.
Authors in the program also have the option of independently commissioning exclusive covers from our artists and paying the artist an up-front flat fee; contact us and we'll help make introductions and coordinate the process.
In either of these situations, the artwork is exclusive to the Storybird project and cannot be sold or used in other channels (though the artist always maintains ownership of his/her artwork).
Additional options for exclusive artwork and limited edition artwork are coming soon.
