I have a photo taken on the street in Vienna, Austria of an adult male walking past a billboard that contains photos of several semi nude models for a clothing ad. I have some concern that I did not have the person's permission who was walking past the billboard nor the permission of the models depicted on the billboard or of the sponsor or ad agency. I was going to enter the photo in a local photo contest in the United States. I was wondering if anyone had any insight into this problem.
