I have attached a scan of the cover and photograph of a picture taken in Hannover in 1878. We believe the young lady to be a sister to my Great-Great Grandmother (Catherine Sophia Dorothea Wilkering) who immigrated to the US from Germany (Schaumburg-Lippe?) in about 1868.
While we do not know the young lady's name, my question has to do with her attire. What is the significance of her outfit with the fore-sleeves and the head covering?
