We purchase all rights to the artwork we contract. We do not purchase first publication rights only, or artwork that has been previously used elsewhere. These conditions will not be changed, so no need to ask for an exception. Payment is based on the size of the art in the finished product, not the size of the original piece. It, along with deadlines, will be worked out with individual artists as artwork is commissioned.
Opportunities are likely to be few and far between.
If you send us samples and don't hear from us, don't panic.
