This excellent catalogue is brimming with interest:
In 1955 cycling clearly requires top-class knitwear and a hair style that would make Elvis swoon (scan 1). Who needs a 3D printer when you can fashion forms like that with nothing more than a plastic comb, human hair and a metric tonne of Brylcreem.
There’s a fine photo of the Terrot factory on scan 2 featuring dramatic lighting and recurring geometric forms.
Simplex gears are everywhere, from the roadsters to the (very classy) Cyclotourisme (scan 4) to the stripped down racers. Terrot is definitely sticking by its Dijon neighbour.
The light-touch drawings on a cream background give a high quality, but even for 1955, slightly dated, feel. I rather like them.
