Blotter art are the designs printed, hand-stamped, or hand drawn on paper before sheets are dipped in a liquid LSD solution to absorb the drug. A single sheet of blotter paper, typically a 7.5 inch square, is divided into hundreds of pinky-nail sized squares for distribution, which users dissolve on their tongues. The writer and cultural historian, Erik Davis, in collaboration with collector Mark McCloud, who has the world’s largest archive of blotter art, has written a new book, Blotter: The Untold Story of an Acid Medium. This week The Microdose spoke with Davis about the history of blotter art and how it’s evolved over the last four decades.
