Renauld's best-known sunglasses are the Mustang, immortalized in the opening scenes of 'The Italian Job' (1969). They were manufactured between 1965 and 1969, and are extremely rare today. They were made with gold, silver, white and aluminium frames and are notoriously fragile, probably explaining their scarcity. Not surprisingly, they are much coveted and exceptionally expensive.
The following photographs are from the Renauld Collection, and further below are images from a collector in Scotland (note the pristine condition and a welcome sight of the original box they came in).
