Interesting “Danger Acid” Sign

Designed and printed by The Communications Company, this sign was apparently used by The Diggers to warn concert-goers that LSD might be dangerous. Little is known about this piece, but there is a clip from a YouTube video of the Longshoreman’s Hall Acid Test where this image appears—we have included a screen shot of this in the images. We sold this exact sign in our Spring 2018 auction, where it realized $575.
