This lovely photograph is of Alma on the occasion of her confirmation in the Lutheran Church. I myself was confirmed as a Lutheran at about age 16, but I went through the classes later than my friends. So I am guessing Alma is between 14-16 years old here. The photographer was J. A. Hayden or Layden of Lincoln, NE.
Alma’s dress looks to be a white batiste or lawn creation with pleats and tucks everywhere. This type of dress was popular between about 1905 – 1920. The big bow in her hair is suggestive of the teens.
