"What is the invisible age? To a large extent it’s a phenomenon of our society, which sees and values younger women for their beauty and energy. Our society also sees and values older women for their wisdom and character. But, in the eyes of this same society, the 50ish to 65ish woman is of little value and practically invisible."

The Invisible Age is a traveling exhibit curated by Jan Potts and Beth Kientzle. The self-portraits of the 31 women photographers express how it feels to be at the "invisible" age for women in America — between 50 and 65.
