I have my first film in festivals and it has won several awards. It is an "art house" short documentary. Is there any value to me making posters for the big festivals (Dok Leipzig, etc), and if so what is the best size? 11x17? 18x24? are postcards more effective? 4x6? basically, can anyone recommend the least expensive marketing tools that are useful in getting people to see your film. Thanks! http://themarinaexperiment.com
