January, 1969. 4 5/8" x 7". Country Joe and the Fish Postcard. BG155. Joined by Led Zeppelin and Taj Mahal.

At the beginning of 1969, Led Zeppelin had not released any albums, and had only  played together for three months. At year's end, they had released two albums, with Led Zeppelin II topping the American charts for seven weeks. This three-day January gig was of immense importance to the young group.
