In 1957, Ducati took the top 3 places in the Spanish Grand Prix 24 hour race at Montjuich. Ducati raced 125's in the sports class with 3 different 2 man teams piloting. Ducati was definitely the absolute winner. The winning team had Bruno Spaggiari as pilot 2, the second place team had Franco Farne as pilot 1. As shown in the photos on top of the jelly mold Elite 200 used blue tank and the restored red tank from a 200SS. Also added a photo of the later version with Ducati in the gold circle and individual plaques underneath with the year and class won. The tanks and 1957 Montjuich race poster are for reference only. These stickers aren't die cut, so you should trim the excess clear background and part number away before applying them.
