The de Young Museum in San Francisco’s latest exhibition, The Summer of Love Experience, takes patrons back to the summer of 1967 where artists, activists, writers, and musicians gathered in San Francisco’s Haight-Ashbury and created a unique counter culture and movement that defined the era. Celebrating the 50th anniversary, the exhibition features over 300 artifacts ranging from hippie fashion to colorful concert posters and other interactive visual and written works created during this time. The exhibition will be on display from April 8 to August 20. Photos by Jessica Christian/S.F. Examiner.
