What I know is that the troc uses the poster within the venue. I have seen my stuff hanging in the club. Around town they make photocopy flyers. If they can, they will make them from the poster. I know my Rollins Band poster was used that way. In fact they mailed them to surrounding counties.
Is there a difference if the band hires one artist to do a tour poster? One poster design, but the venue info changes. The poster is sent to promoters and is sold at the merch table. I have never seen an argument over that type of deal. The only real difference I see is you get 3 great artists designing a different poster for each show. I don't see that as a problem. A monopoly? Is there such a thing in poster art? The band wants them to do this. It beneifits a lot of people. The band gets promotion as well as the artists. A printer now has a steady flow of work for a month or so. Collectors and fans will love this idea. This is the american way! GOD BLESS AMERICA!!
