Original 1st printing (OP-1 in the Eric King Guide, this is the version with the blue/green ink mark in the lower left corner) 20 x 14" event poster for the 4/15/1967 Haight-Ashbury neighborhood "Clean-In" (the local "head" community took to the streets armed with brooms and dustpans to clean up the neighborhood and to raise awareness for the 1967 Spring Mobilization against the Vietnam War).

 Art by Victor Moscoso, image is # 15 in the Neon Rose series.

 Medium flat index stock poster is in absolutely fantastic mint/near mint to near mint (A/A- to A-) condition; a VERY crisp/bright 1st printing example of this early-1967 Haight-Ashbury poster with a killer Moscoso design and eye-searing colors.
