This was found in the Saint-Ouen flea market, near Jules-Valles. Phosphatine was apparently a soup for children, an all-around curative for growing bodies.
I've added two more that I picked up at the Jules-Valles stall. There are no dates, but the reference to Indochina as a French Colony could indicate the late 1940s, early 1950s... Could it be earlier? Don't know. Remember to left click to enlarge image.
