No, that's not a mirror! It's the twins, Martha and Margaret.
The Twins
Martha Isabel and Margaret Adele were the twin daughters of
Herman and Ida May Weyland. By a stroke of good fortune, the
owner of the Ross photo studio in Tipton was a neighbor of the
Weylands and, intrigued by the unique opportunity to photograph
identical twins, Mr. Ross took a number of photographs of the
girls. Some examples appear below and on the following pages.
With a little practice, it's actually easy to tell the twins apart.
Margaret's face is slightly more rounded than Martha's and her
cheeks are fuller. Martha's chin is a bit longer than her sister's.
