I believe that this is a business (or advertising) card handed out at a French trade show in 1949. It shows that:
At the time, the full name of JIC was ‘Societé JIC-Champion’.
It had previously been called ‘Établissement Veuve Charles Jeanmot’ which might roughly translate as ‘the establishment of the widow of Charles Jeanmot’.
JIC was based in Puteaux, a suburb North West of Paris, not a million miles from Nanterre, the home of Huret.
When listing its various lines of business JIC puts manufacturing derailleurs first and in the largest typeface.
Amongst JIC’s other lines of business, I can understand the special racing frames and wing nuts but what exactly is a ‘home-trainer médicaux’?
