As FYI... you may want to contact Harpers to see about the implication of putting your copyright on printed work such as magazine cover published by Harpers, as most likely the image and the cover are copyrighted separately. I'm sure it is located somewhere in your contract.
I Don't quite understand what you are talking about and I am not concerned. My relationship with them is exemplary.
