Bolex M8 brochure
3 3/8" x 6": folds out to 13 1/4" x 9". Switzerland: Paillard Ltd. (1950).

I don't know if this is the first brochure for the Bolex M8 Projector, but it's the earliest I've come across. This one was printed in 1950 and shows the original olive green colored model with a Kern 20mm f/1.6 lens. The voltage differences of the M8 and M8R are also described, among other basic features.
