Gaston Doumergue (June 1924) in a Renault 40 CV
Scan from the photo historic book "Honderd Jaar in de Topklasse: Hulde aan de Safrane" (Dutch; translation: "Hunderd Years of Premium Class Models: A Tribute to the Safrane"). I'm not sure if this book was also published outside the Netherlands (but I think it was), but Renault published it to go along with the introduction of the Renault Safrane. It includes numerous rare photographs and a long description of the development of the Safrane. Louis Schweitzer himself wrote the preface.
