Most of them are German EDI dolls. EDI stands for Erich Dittman who manufactured dolls 1948 to 1960. The dolls were made of celluloid or tortulon (a kind of plastic) and dressed into many nationalities. Also characters from fairy tales were made.
On one of my dolls I have found an EDI marking in the neck of the doll. Some of the dolls have their clothes glued to their body so it is impossible to check for any markings.
This Scandinavian couple or perhaps Swedish, was sold in Sweden at least in the mid 50s. I have some more dolls similar to this couple but only one complete couple, as far as i know. The other ones missing some parts of their clothing
Here are guests from Germany I think. They arrived just a couple of days ago and are my latest purchase to my doll house world.
