An ad for Classic silent film convention in Italy. When I think of silent films i instantly think of Charlie Chaplin and coincidently so does the ad agency that created this poster. Charlie Chaplin was most well known not just for his movies but his hat and moustache. They've incorporated representations for both sound ( the speaker ) and silence (Charlie Chaplin ) I like how they have used the speaker symbol to create his moustache as well. Simple but effective.
