Robert Nicholas.
I don't have a clue to when this was taken, but it must have been around 1900. It was taken in Ishpeming Michigan at the Child's Art Gallery. ;-)}
Robert Nicholas' lapel pin. It has to be a picture of his sister Clara especially at the resolution I scanned it (600 dpi). See picture of Clara below.

Clara's picture was taken in England and Robert's was taken in Ishpeming Michigan. What's the button about?
