I may be mistaken - but I think Wobbly John of this forum has a blue racing style bike with a Campagnolo logo on the frame?
Actually I've got a couple of Campagnolo transfers myself - they came with a 1989 Raleigh Team replica frame. They are intended for use on the chainstays I believe, so that you could have your bike look like the ones the pro's rode, which had the component manufacturer displayed as advertising I guess.
