The purpose of these post cards are to promote the film, they can be handed out at various locations. People usually pass these around and tend to keep them after the event as a memory. As far as I have researched I have figured that every film post card has these elements in common. – They have a poster with large orientation this gives audience a glimpse about what the movies about . – They have their movie name on it, A title is also something very powerful element , if used correctly it can attract a crazy amount of audience towards your content. – It contains the most important date for the viewers which is the release date and or the date of premier. – It also contain the watermark of a film festival if thats a film festival movie and has been nominated by that film festival.
