Sorry Marco, I don't understand why you think I'm confused. You seem to be repeating exactly what I said - here's my quote: The guy wasn't selling a model from Disney, he designed a model based on Disney's work and was distributing it for free. And Disney had a problem with that. Happily, they reached an agreement. For sure it's not forbidden to re-sell a model, that's "first use doctine". The more specific question is whether one can re-sell an assembled card model without the designer's permission. In the thread I linked to, a copyright lawyer said an assembled card model would qualify as a "derivative work" (which, under American copyright law, requires permission to re-sell). Whether or not an assembled card model is categorically a derivative work, I personally can't say. My original point was that a lawyer who specializes in this type of law said it is a derivative product (and thus requires permission)... so it would be a good idea to get permission to be on the safe side. After all, getting permission only takes an email. And that's another good reason for designers to put URLs or email addresses on models. However, you raise a great point - it is unlikely the original designer had permission from the owners of the Battlestar Galactica copyright! I'm sorrry I missed that, I'm not a big science fiction fan and didn't realize what "BSG" stood for. You are absolutely right, permission would be required to legally distribute a "BSG" model, even a free one. Typically, media corporations overlook so-called "fan art", for a number of reasons (for one, it's usually not worth their time to track down and prosecute). But as the well-intentioned fellow who designed the Disney model discovered, there is risk involved. It's hard to compare card models with plastic models because with plastic models you can only sell one assembled model for each one you purchase. That's why "first use" is much more clear-cut with plastic models. But with a (digital) card model, you can assemble as many as you want from one purchase (or one free download, whatever). In this way, the purchaser/downloader can actually produce more copies of the original product from a single purchase. That could be a problem, even with free downloads, as you could be infringing on the distribution rights of the designer (e.g. you could be depriving a designer of site traffic from which he benefits financially). It would depend on the copyright in question, and what it specifically allows. And that brings us back to the point I was trying to make: it's important for designers to put copyright statements on their sites and on their models so it is clear to the builder (and anyone else) what is possible without permission. Exactly - just as I said earlier in my reply to paulhbell. However, as I said, if you started selling copies of the movie posters without permission, or used them to produce some other commercial work (e.g. a book of movie posters) without permission, that could be copyright infringement. And those are the potential copyright issues involved with the issue of re-selling an assembled card model.
