Charming vintage card given by teacher May Norton to her student Mertie Ludwick. Sadly, no location given.
And there was a Myrtle Mary "Mertie" Ludwick who was born in 1886 or 1887 in North Plains Township, Michigan, the daughter of Harvey Milton Ludwick and Emaline Melinda (Dick) Ludwick. Mertie married Henry Harder. She died in 1952.
And there are perhaps several other Mertie Ludwicks across North America. Again, if you have a theory as to the identities of student Mertie Ludwick and teacher May Norton, please leave a comment.
