My previous post about innovative advertising spaces featured paper hangers, rental bikes and even human bodies as carriers of advertising messages. Here is an example of a very original outdoor advertising solution that was used to promote new hot breakfast sandwiches by Caribou Coffee in the US.
The ad was placed inside of bus shelters in cold Minneapolis. I bet that standing in an imaginary stove made people waiting for the bus feel warmer -- and make a mental note about the buns. Very creative and memorable!
