This is another advert which i have researched and that has continous coventions that other HMV adverts have. The qualties that they have in comon are

-Three colour system

-Usage of symbols and slogans

-Variation in text size and colour
-Contrasting colour

-A selection of images ( i have used this convention in my poster)

- To make it seem more realistic and to abide by copyright issues i have included small print at the bottom of the advert
