To promote their exhibition stand at the Frankfurt Book Fair, Eichborn the publisher with the fly prepared 200 flies with an ultra light banner. The banner was attached with natural wax. After a short time the banner dropped off by itself. And the flies were not harmed.
The concept is certainly remarkable, if not unforgettable, but whether those experiencing this viral campaign remember the company name as well or just the fact that they saw flies with adverts attached to them is another question?
I first saw this on the Unionversity website
