French rock and roll star Johnny Hallyday will auction off a classic Cadillac and a Harley-Davidson for charity in Paris on February 10.
His 1953 Cadillac Series 62 Cabriolet, featuring coachwork by Boyd Coddington, is valued at $52,000.
The car is actually one of the last that legendary hot rod builder Coddington worked on before he died in 2008.
Hallyday is also offering his 1990 Harley-Davidson Softail Springer 1340cc, which is valued at around $20,800.
Each of the lots will appear in Artcurial's much anticipated Retromobile 2017 sale.
Hallyday is one of the biggest French language singers of all time. He's sold around 80m records worldwide.
To place it in context; that's more than the Black Eyed Peas and Kenny G, but slightly fewer than either Tom Petty or Barry Manilow.
Matthieu Lamoure, managing director of Artcurial Motorcars, said: "We are absolutely delighted to be helping Johnny Hallyday, who has always loved beautiful old machines, to support Laeticia's charity, by offering his unique and well-known custom Cadillac '53 and his Harley that has starred in so many photographs and on his albums.
"The bidding will be open to anyone who wants to support a good cause, those who love Johnny and all fans of beautiful machines."
