A very pretty woman with big dreamy eyes and dark hair poses for her portrait at the McKnight studio, in Centrailia, Illinois. The woman is wearing a dress that has four very large buttons at its top and smaller buttons below. The large and small buttons appear to be identical except for size. The decorative buttons show grapes or berries. The woman is also wearing a flower and earrings, as well as a pin at her collar. The pin features the letter “H”, which may be the first letter of her first or last name. The photographer of this image may be Frank McKnight or P. McKnight. Both of these individuals are listed in a directory of Illinois photographers as operating studios in Centralia during the cabinet card era. This photograph has a crossed out location on the bottom of the image. It is probable that the photographer formerly owned a studio in Missouri and moved to Illinois but kept his stock of pre-printed paper. Although it is easy to decipher the state, the town is blacked out beyond the point of recognition.

The town doesn’t seem to be too blacked out on my screen…I’m wondering if it is Chillicothe in Missouri.
Even her earrings seem to show grapes, the buttons grapes and birds – maybe for some religious, maybe for some sentimental reason about her family; because of the earrings I don’t think, it was just decorative.
I think, the fresh flower might be some kind of Viburnum.
