The only classic car show worth visiting (for Lancisti that is) is the one in Padova, each fall.
In 2003 there was a stand with Fanalones in all available colours, except Rosso Corsa. The cars on display had the following colours: Blu Jamaica- Rosso La Plata- Bronzo Longchams- Azzurro HF- Bianco Saratoga- Amaranto Montebello- Rosso Italia- Grigio Escoli.
If your italian is any good you may look it up on
