I know this is authentic, because my mother obtained it after a 1953 play in Hinsdale, Illinois (outside of Chicago) when my mother was a 13 year old girl. She got it signed after the show (June 7th production of "Years Ago" at the Salt Creek Summer Theatre in Hinsdale). The back of the photo has "Dortha Duckworth, Momma" written in pencil my grandmother's handwriting. (Dortha Duckworth was in the show as well). It is a 3.5 x 5" b&w photo, signed in blue ink.

I was curious if anybody could tell me what a value would be on this. Thanks---
