As an artist, I should be disgusted by other people making money off of my work... but if I created a custom marquee, and someone that I *gave* it to was making money off of it, I wouldn't care.
Here's the deal.. if classicarcadegraphix takes care of us, and does excellent work, and treats their customers well, I don't think it is unreasonable to give them a few freebies. I don't create marquees, and trace artwork to make money. I do it to make myself happy. I don't create a ton of it either, just a little here and there, so it's impossible for me to really consider it a money making venture. I'm generally against other starving artists/designers doing clip art, because it takes away from the ability for *real* professionals to make money on custom art. In this case, there are no professional marquee designers (at the consumer level, anyway) So, in general, supporting a good company in this way makes sense to me.
As far as copyright... I can't expect to make royalties off of other people's artwork that I traced, manipulated, and repurposed. If c-a-g.com wants to make money through what is effectively *pirating* then that's up to them. At a mom and pop level, I don't see a big issue with this type of copyright violation. Even as an artist... I know it could could be ravenously argued both ways. I guess my ethics only extend to a certain point.
