The Margarine Arcy dates from 1955. It is "the emblem of the Alsatian jewish cooking". The reason is simple: this margarine is "kosher". (see here). This company still exists nowadays.
Concerning the "great circus", do not look anymore for figurines, they do not exist. On the other hand, the blotting paper announcing this event is real!
When you were sending 10 Arcy voucher, you you were then receiveing an envelope (here) with the explanations of assembly (here) in the back.
