A collection of cars from the 1920s highlights one of the greatest eras of car design

Unless your name is Jay Leno, car collectors tend to focus on a particular theme when selecting examples.

Many zero in on a manufacturer, category, country of origin, or, in the case of one lovely collection to be auctioned in Monaco this weekend, an era.

The sale will take place at an RM Sotheby’s auction on May 14 which runs concurrent to the historical Grand Prix of Monaco.

Interestingly, all lots are offered without reserve.

The “Quattroruote” collection is the child Gianni Mazzocchi, co-founder of the widely-read Italian motoring magazine of the same name, Autoevolution reported.

Along with a good variety of other vehicles, like a World War II-era Jeep, an 1879 Singer racing bicycle, and (rather oddly) a 1978 Mercedes station wagon, the collection boasts an impressive selection of vehicles from the 1920s, perhaps the most influential era of automotive development and design.

The auction highlight is undoubtedly a head-turning Bugatti Type 57 Cabriolet with coachwork by Gangloff of Colmar. It was once the famous French automaker’s showpiece, and is sure to capture a sale figure with many, many zeroes.

Take a look at some of the other vehicles for sale.
