Vintage WMF Babybesteck 3 teilig Cromargan. This was a German 3 piece baby cutlery set with fold out story, song. 1 piece is missing, there are only 2: silver spoon and food pusher. Both have little ducks on them and are marked on the bottom. See pics for measurements. Top has a fold out paper duckling scene from a little duckling German song. Included pics of translation, so cool! P-A7
