Gillette Writes World’s Smallest Ad on Whisker

In a move that defies all conventions of ad design, razor maker Gillette has created the world’s smallest advertisement. Using an electron microscope, an ion etching device, and some University of Nottingham scientists, Gillete wrote a series of ads smaller than 100 micron on whiskers shaved with their razors. Once completed, the Guinness Book of World Records was called in and confirmed that these are, indeed, the smallest ads yet created.

Wanting to appeal to an audience larger than dust mites, Gillette used images of the hairs as part of a larger campaign. They’ve even placed several of the etched hairs in airport mens’ rooms with QR codes linking to images of the ad.

Read on after the break for a video on how these tiny, tiny ads were made.
