Thanks again guys...I love your input on this. All my artwork are from photographs of some sort and I change things up and paint in my own style. I never make it look like the original photo so I've never worried about copyright infringement before. I think it's because this mural will be very public and directly related to a business, the concerns have come up.
I am heading down the path of generic images and silhouettes but they just won't have the same impact as a likeness image will have. I don't paint like Jackson Pollock and I know the public here prefers murals that look like something and to have a few images that they can relate to always comes with a lot of positive feedback...that's what I'm aiming for.
This mural is very important as it will be a flagship mural for me in my community and city and I want ot put my best work on display. Sooo, you can understand my dilema.
Well, I'll have to come up with something. Thanks again for your input.

ps: I contacted a couple of attornies but of course they wanted $$ in exchange for their advise...argh!
