The Haddock Convertible – “The 7 Crystal Balls” (1948) Enraged by the kidnapping of Professor Calculus, Captain Haddock finds all his energy when the police informs him that a car mechanic has seen the kidnappers’ car go towards Saint-Nazaire (see page 54). Accompanied by Tintin, he sets off in their tracks at the wheel of his beautiful American convertible car. The only car ever owned by Haddock, the Lincoln Zephyr is among the first aerodynamic models of the 1930s. Its elegant curves and fluid shape allow it to roll at high speed. Nicknamed landplane by its creators, this model will revitalize the company Lincoln bought by Ford in 1922 for $ 8 million.
