Berkeley & San Francisco, CA: 1964-1964. First edition. Original wrappers. 8 1/2 x 11 inches. Very good. Synapse, edited by D.R. Hazelton, ran for four issues out of Berkeley from 1964 to the Poetry Conference the next year. Synapse is actually not mentioned in Clay and Phillips, despite being a Left Coast mimeo. The third and fourth issues were edited under the supervision of Gary Snyder.
