antique BMW Folder (1939) Posted on 08/02/2015 by philipp BMW Six-Cylinder Folder 1939 Here are some pages from an old BMW folder I own, it is titled: “2 und 3 1/2 Ltr Sechszylinder”. The folder was printed in 1939 The color paintings of the cars have transparent overlays with information about interior dimensions. Even before the second world war fuel consumption was an issue, here is a graph showing the relationship between l/100km and speed. One of the most successful racing-cars of it´s time, the BMW 328 “Sportwagen” According to information from the BMW archive this means that the folder was printed in February 1939!
