Greenfield, NY: Greenfield Review Press, 1971. First Edition. Inmate writings from Soledad State Prison. Reproduces many works from the surreptitious, inmate-produced anthology The 6:15 Unlock (of which only ten copies were produced). "These writings were smuggled out. They are anonymous to protect the prisoners themselves" (from the editor's foreword). An enlarged Second Edition was issued by the Crossing Press in 1974; the first edition is somewhat uncommon. Octavo (22cm). Staple-bound, illustrated card wrappers; 67pp. Tiny crease to front wrapper corner, else fine.
