Wow, who would have known?? Thanks for the post Wolfsnap - copyright issues are a big problem, more so to photographers than other artists. I know when I was shooting "up and coming" rock bands - I always had to ask the guys to NOT wear T-shirts with any promotional ads on them, as it could cause problems with copyright violations. Thanks to your great information - If I ever go to Paris, I will be make sure all my shots of the Tower are created in the day light hours :) Dee-Marie
