I have to share some papers with you that a friend is letting me look at. It is a sample book and a small monograph. We don't know if all belongs to Berta Frey or not...... but that is her handwriting on the blue paper!!!! The small monograph in the blue paper has the copyright date inside as 1947.
It's finding stuff like this that makes a weavers mouth water. Thanks, Sam, for sharing this with me.
