Do you have the right(s)?

Here's a lesson in getting rights to assets that you use in a project.  As reported in AdFreak an Illinois gun manufacturer used an image of  Michelangelo's David in an ad holding one of their weapons (it's huge, and I'm not talking about David) causing the Italian Culture Ministry to issue a warning to retract the ad since technically the government owns the statue.  Never take for granted the use of an image even if the subject is something very well known or common place.
