Placing posters on a vending machine at the National Office of Public Health with a skinniness-evoking image (Giacometti sculptures) or an activity-evoking image (running legs in sport shoes), instead of a pleasure-evoking image (two carousels with a summery blue sky) or no poster, led customers to purchase more healthy snacks (58% and 44% versus 29% and 21%, respectively).
