Well, for one thing, that decal style (with the WC stripes incorporated) is later than the frame details, in particular the long Campagnolo dropouts and full complement of heart cutouts in the lugs. (The black heart decal on the seattube also looks pretty cheesy to me, but that's just my sense.)
I'm interested to know if Citoyen du Monde thinks the chrome fork is likely original, or if it was chromed when the repaint was done.
