I took some photos at a regional Native American Pow Wow last summer. It was a public event and I was allowed to take photos openly, except during certain dances when I was told to stop. Although open to the public, the dance ground was on reservation land which comes under Federal laws since tribes are soveriegn nations. An advertising agency wants to use one of those photographs on the cover of a free tribal tourism guide. They picked the photo from a Google search. It shows a partial side view of a recognizable face, name confirmed by several tribal members I contacted. Unfortunately, none of them have been able to reach the man to have a release signed. I'm worried that he did get the message and just isn't going to contact me because I'm not a tribal member. I took the photo's for my personal use, but offered the entire group to another affiliated tribal agency for their promotions use as well (I've worked with them before). The free guide contains advertising inside, but is mostly travel and promotion using other photos submitted by several featured tribes. I don't think a law suit would get very far, but it would end up in a federal court with a paid tribal attorney representing him. I'm flat broke. On the other hand he's one of two featured dancers used by all the tribes in three states and should welcome the publicity. ARRRG. Do I yeah or nay the agency to use the photo?
