Go to http://www.raydobbins.com/medici/index. The date references on the site are not consistent, however (1970s or 1984).

I remember looking at Medici catalogs for hours, and driving to New Jersey from Boston to see them at the east coast distributor/seller. The history is fascinating; the Masi and Confente connection is worth knowing, so look up the Mario Confente story online.

You might also contact some of the large refinishers, like CyclArt. They may have the decals you want.
