“Cold Call” Marketing
With a wide swath of North America buried in snow and ice, Wax creative agency in Calgary, Canada, adopted a different medium for outdoor advertising — frost. To promote Mucho Burrito restaurants as the place to go for sizzling hot food, Wax created a block stamp that left a message melted into ice-coated car windows. It’s eco-friendly and beats sticking soggy paper flyers under windshield wipers.
