This question of copyright keeps coming up and keeps coming up. It's a legal minefield these days. The lawsuits keep piling up, as Big Corporations step down hard and strive to make their footprints ever deeper. And it has a dampening effect on creativity, as the collage-fans continue to point out.
I'm part of a group of artists, for instance, who work in collage and found art. It's a big fat problem when someone shows or sells a work that uses some part of, say, a Coke label. The artist was only interested in a shape or a color, but Coke thinks it's an unfair comment on their global hegemony, and sends them a snippy letter suggesting legal proceedings. 'Fair Use', in my view, *should* include using any artwork any way you like, but that's not how it's working out.
I want to see artists fight back, and I want to see Big Corporations lose their power. If you want to take them on, I support you. This fight is a lot like the Range Wars of the 1880's, when big ranches would fence off huge swaths of land, and small ranchers would clip the barbed wire and run their herds through anyway. You can guess how that turned out -- big ranches hired people with rifles to protect their fences; small ranches couldn't hire anybody.
So for anybody who would like to someday sell a deck, you can save yourself a lot of trouble by doing your own artwork. (Which is then copyrighted to you and only you...)
