Hubba Bubba Gum by Numbers

Wrigley’s in Australia developed an outdoor response to gum litter with this collection of interactive posters. Colour by number murals featuring Da Vinci’s Mona Lisa, Marilyn Monroe and Vincent Van Gogh’s Sunflowers, invited passers by to contribute by placing their chewed Hubba Bubba bubble gum. “Gum by numbers. Every little bit helps keep Australia beautiful.”
