Woodstock photos are displayed for 1st time, 50 years later

This August, 1969 photo shows Janis Joplin as she performs during Woodstock in Bethel, N.Y. The photo is only one of hundreds made by photographer Mark Goff who, at the time, worked for an underground newspaper in Milwaukee, Wis. Some were published, but the negatives were filed away at his Milwaukee home and barely mentioned as Goff raised two daughters, changed careers and, last November, died of cancer. Dozens of Goff's Woodstock shots are being displayed 50 years later.
