I bought some of the Campy oval reprint stickers from Mike Kone a year or so ago. They're quite serviceable if you don't mind taking a little time and effort. They came printed on a white sheet, and the die cut oval leaves a white border. If you carefully trim away that border, they look pretty authentic when applied. If you want to see what it looks like, you can see one on my Ryffranck (fourth shot, just below the Columbus decal) in my PhotoPoint album at:
By the way, I'm in the process of putting together PhotoPoint albums of all my bikes. They are not all there yet, but hopefully will be some day. Maybe even some pics of me and my basement shop. So far I have my Pike, Trek 720, and the Ryffranck. Be forewarned! Everything in there may not be classic! (But it might be interesting just the same.) The Ryffranck might qualify as "in the classic style". After all, it's a hand built, lugged, steel tube frame.
If you haven't yet tried PhotoPoint, I encourage you to check it out. It's simple, easy and free. And a great way to share images of all the really cool bikes and bike related stuff out there.
