I have requested a gig form a book cover designer, and they state, in their gig info, that the "Source File" is available in the deal. I take it, that it means I will own the source file 100%, once everything id done, is that so? If yes, on receiving the source file, I can then use it for another of my book covers, without needing to ask the cover designer of the source file, whether I can use it or not, without any legal recourse. Is that correct?
