Purdeys advertisement design

Within this brief Purdeys said they don't have advertisement and that there drink is just discovered, so despite them saying they have no advertisement it would obviously be beneficial for them to have some. So i thought of a way this could be done is to hint at advertisement but isn't so in your face. 

The way I thought would be good is having posters around that don't have the Purdeys name on them but just had colours and shapes that are relevant to this drink i have created. 

So i created these poster which hint at advertisement, they show the circle that is on the drinks and the ingredients thats in each drink. The idea is that somebody will see these and think whats that, and when they next see the bottles they will remember the posters and buy the drink, this then implies that the drink has been 'discovered'. 

After creating this very simple poster i mocked it up so it is in the environment.
