Where can I find a full set in complementary blue that they used on celeste. I need down tube, seat tube, head badge, and the made in Italy sticker. The font style is not that important as long as it was the kind they used at one point or another. Any ideas.

Ditto...my Bianchi will be in need of these soon.

I usually paint almost all of my logos and lettering on the frames that I paint. here are some examples. To do this computer art is created adn then a mask is cut on a plotter to allow painting of any color.

Try Bianchi USA. They won't have anything too vintage but I think they still have late 80's and 90's sets. You might have to get a professional painter to order them for you?

Also Lloyds in the UK has older style headbadge and downtube declas for Bianchi's.
