Ah, yes, girls and their beautiful eyes. Even as an old man, I sigh when I see a girl with beautiful eyes. I love pictures that capture them.
When photography was in its infancy photographers did not overlook the beautiful eyes of young women. One technique at the time, even when they had long exposures was to have the subject look directly into the lens. The man behind the camera would place the field so that a pupil was in the absolute center of the frame. The affect was that the person's look seemed to bore right into you. Here is an example. The tintype was taken in about 1870. The girl is Matilda Davis, the one time special lady friend of Richard Brewer, who was a friend and employer of Billy Bonney aka Billy the Kid.
Matilda and Brewer were planning to marry, but she jilted him and married his cousin instead. Broke the poor man's heart and he left town never to return. This picture was found within Sallie Chisum's person collection of photographs. Brewer, I suspect, gave it to her. By the time he did, he and Matilda had been split for about six years and he probably wanted to put her memory far behind him.
