Shopping bag is an incredible advertising opportunity. Not only can a store use it to advertise its brand (such as Macy’s recognizable star or Target’s bullseye), it can also vividly display a product’s use or spread a message with the placement of one’s hand. Here are two creative bags, one from YKM that demonstrates jump rope and the other warning against the use of plastic bags. Of course, there are many more out there. But I think these two in particular are very well designed in their simplicity and immediately recognizable messages.
