Explanation:

This is the main disadvantage of using a poster in order to encourage people to attend an upcoming concert for a new band. A poster can communicate information about when or where the concert will be. It can also give people an idea of what the band looks like. Finally, it can be large enough for people to be able to see it. However, a poster cannot communicate ideas audibly. This means that people cannot know what the band sounds like, and this might make them less likely to attend the concert.
