NapAds is a pretty cool business that allows advertisers to distribute messages in the form of napkins across it’s network consisting of bars and nightclubs.
The NapAds are provided to the bars for free in exchange for allowing NapAds.com to place NapAds inside their venue. Any print campaign can be duplicated on to a standard beverage napkin.
Perspective: This is a good medium to reach the often hard to reach demographics. I think raw drawings would work well, as many of these places are dark.
