I realise that this proves nothing, and that since I've never seen an old ghibli in the flesh I have almost no legs to stand on, but I'm inclined to err on the side of rOeLez here. I just did a google image search for "campagnolo ghibli hub" and browsed the photos of old ghiblis. Two things I noticed is that none of the wheels in the google search seemed to have the same hubs as the Rossin (minimum 4, usually 6 bolts compared to 2/0 on the Rossin). Also, I'm not sure any of the google ghiblis had the same shape valve holes either. Not saying it's not real, and that campag can't go altering the details of their wheel design, but I didn't see any wheels that looked to be a true match to those in the advert.
