Pupier was a French chocolatier that included trading cards with its products. In 1938, they depicted scenes from countries including Palestine featuring religious sites, views of Jerusalem, a map and a Zionist flag. Another card depicted the camp at Ben Shemen: founded in 1927, and still running to this day, the youth village and agricultural school counted Shimon Peres among its students. The back of this card—remember, this was 1938—calls it “a Jewish colony for children, located on the outskirts of Tel Aviv, where a number of young German Israelites are grouped together, having left Germany as a result of political events.”
