At 13 Mark Cloud tried acid in Santa Barbara, an experience that merited the epic summation: “I was blind, but then I could see.”
It wasn’t until then, around 1968, that acid imagery became popular and McCloud started collecting and cataloguing the many acid stamps he encountered.
“At first I was keeping them in the freezer, which was a problem because I kept eating them,” McCloud explained to VICE, “but then the Albert Hofmann acid came out, and then I thought, Fuck, I’m framing this. That’s when I realized, Hey, if I try to swallow this I’ll choke on the frame.”
Today, Mark McCloud is the world’s leading collector of “Blotter Art” (the fancy way of saying that he collects the small, stamp-like papers that used to transport acid, or LSD). McCloud’s collection, one that is bigger and more varied that those owned by the FBI and DEA, is now hanging in his Victorian home in San Francisco- a home turned museum that you should definitely visit!
