I've got a commissioner whom I'm making a suit for, but the suit is based on a copyrighted character. This wouldn't normally be an issue, as I'm basically just building an animal suit, but now I'm finding out that this commissioner owns a mascot/costume company where they do costume rentals and appear at parties. And I'm starting to think that I might actually be making a copyrighted character for this use. If a suit is made for commercial use like this, what does that mean for me, the artist?
EDIT: I feel like I should clarify on what I'm asking, exactly. While I'm certainly interested in the legalities of producing a generic costume that could be turned into a copyrighted character and used for profit, I'm actually more interested in whether or not producing a suit for a business/for use in making a profit would merit an additional charge from the artist? This edit is probably too late to get a response at this point, but there you go. :p
