Heinz Tomato Ketchup This ad shows the need to satisfy curiosity. It shows this by having the ketchup bottle look like slices of tomatoes. Which satisfies the curiosity that it is made with real tomatoes.
I really like this poster. The shadow of the hand and cigarette appears to be a hand holding a gun. It would look even better with smoke coming out of the cigarette, making it look like the gun was just fired.
