History provided courtesy of Marcel Massini:
Chassis #0221 EL is a very special car. This car wears a one-off coachwork by Vignale and is also the official factory brochure car for the type 212 Inter. Sold new in Switzerland this automobile remained there for 51 years with just 4 owners, the last Swiss owner keeping it for 40 years! Although it has been repainted the car still is in the original colors of ivory with a dove gray roof, exactly as born in May 1952. The Factory Certificate of Origin is signed by company founder Enzo Ferrari in his legendary purple ink and this alone is a super rare item. I don't know of any other Ferraris of this early period that have the Certificate of Origin signed by the famous Commendatore himself.
More pictures soon.
