Vinyl sticker, "Fly". In 1974(?) the American publication, 'Cycle World', conducted a road test on a bevel twin Ducati. One of the noteworthy parts of the test included the commentary on the accidental inclusion of an honest to goodness fly in the gel coat of the petrol tank. Italian quality control at its finest!
Your chance to tip your hat to the Ducati artisans of Borgo Panigale.
