Hi! I was considering designing some tee-shirts to promote the television show Supernatural, which I think is woefully under-promoted, but I don't want to violate the CW's copyright. I'm not going to use any copyrighted images or anything, but the designs would of course reference the show - for instance, a silhouette of a '67 Impala and the phrase "My other car is the Metallicar", or of a Winchester rifle and the phrase "Salt and burn", or possibly even quotes from the show. I'd also like to add a tagline of "Watch Supernatural" to the designs. Does that sort of thing violate copyright, do you think?
I don't expect to any money from this, and if I did, I'd undoubtedly just use it to buy more Supernatural stuff (
like sending Season 1 DVDs to the troops), but I really don't want to annoy the copyright holders of the very show I'm trying to promote.
I'd appreciate any thoughts or advice on this, and thanks very much for your help!
