Mark McCloud is an artist and ex-art professor who has been collecting LSD blotter art for over three decades. He has curated exhibits featuring pieces from his collection (the world's largest), lectured at conferences on the topic, and has won two grants from the National Endowment for the Arts. Many of the prints in his collection, housed at The Institute of Illegal Images, were never dosed; those that may have been dosed are exposed to ultraviolet radiation to neutralize any acid that they might have contained. Because of his collection of unique American Folk Art, McCloud has been threatened, set up, subject to surveillance, and busted by law enforcement. McCloud was arrested twice by the federal government on charges of "conspiracy to distribute LSD"--first in 1992, then again in 2000. He was acquitted in both cases. McCloud and his business partner Dana Dana Dana currently deal in limited edition giclée prints of blotter images--massively enlarged, pulpy, and vibrant--via their Blotter Barn web site.
