A publisher has come up with a novel way of advertising their books… by attaching adverts to flies.

The bizarre advertising campaign was launched (quite literally) by Eichborn at the recent 2009 Frankfurt Book Fair and involved somehow tying tiny ads to the flies legs.

This meant that as the fly took to the air, little banner adverts - which were light enough not to weigh the flies down - appeared to float around the halls.

While the final result certainly looks impressive (check the video after the link) please spare a thought for the poor German work experience kid who probably spent hours the night before tying the adverts to the flies.
