We could divide this big series into two at the level of the rarity. Indeed it is possible to find the references from 1 to 25 (excepted 17), but he(it) is extrèmement difficult to find the rest. No explanations besides the Rhine to this day.
Meyer is a German brand of Margarine and these figurines date the 50s. It is really necessary to linger over details, as small mouse under the table of the number 34.

Greats Thanks to Helmut Bisch for the pictures
