The three Italian campaign posters are labelled Make together, In sourcing, and Crowd sourcing. Each poster combines text with a sea turtle among plastic waste, joined hands, and messages about environmental protection and helping families in difficulty. The Make together poster states that 1 per cent of product sales revenue is donated to the MIGLIORInsieme association. The In sourcing poster states that accumulated loyalty points are donated to the association. The Crowd sourcing poster states that returning the empty bottle to the supermarket supports the association.Experimental stimuli
