Envelope reads, "Livermore Radiation Lab. Pacifists & opponents. 12/21/61." Negative shows a small group of men standing in front of the parking lot in front of the University of California Radiation Lab, Livermore Site (sign above the building says this) [Lawrence Livermore Lab]. The men are holding picket signs and wandering around. The signs says "The 'Peace Vigil' is Communist inspired" and another "NO peace on Kruschev's terms." Behind the men is a VW bus driving into the parking lot, two men working on the back tire of a Chevy pick-up, and two cars. The Lawrence Livermore National Laboratory, which specializes in weapons research, was built in Livermore by the Atomic Energy Commission in 1952 and under the management of the University of California and affilated with Lawrence Berkeley Lab until 1971.
