A clothing store in New Zealand has installed plates on local benches to imprint their advertising on the backs bare legs. The ad agency that put it all together explains:
We put indented plates on bus stop, mall, and park benches, so that when people sat down, the message was imprinted on their thighs. This meant that as well as having branded seats, a veritable army of free media was created, with thousands of imprints being created and lasting up to an hour.
Interesting idea, but I don’t think that companies should use people’s bodies for advertising without their permission.
