Mark Mc Cloud

McCloud's home, The Institute of Illegal Images, is a museum and archive dedicated to the history and culture of LSD blotter art. Located in San Francisco, California, the museum houses over 33,000 pieces of blotter art, as well as a vast collection of related ephemera such as books, posters, and other materials.

McCloud's role in the development of blotter art can be traced back to the early 1970s when he began experimenting with the medium as a form of drug ingestion. He quickly recognized the potential of LSD blotter art as a form of artistic expression and began creating his own designs.

In the early days of blotter art, most designs were simple and utilitarian, featuring only the necessary information about the drug dosage and potency. However, as more artists began experimenting with the medium, the designs became increasingly elaborate and visually stunning.

McCloud was instrumental in helping to promote and popularize LSD blotter art, both through his own work and his efforts to document and preserve the work of other artists. He founded the Blotter Art Project, an ongoing effort to collect and document LSD blotter art from around the world, and has worked tirelessly to promote the art form and educate others about its history and cultural significance.

Today, blotter art is a highly sought-after collectible, with pieces fetching high prices at auction and through private sales. McCloud's contributions to the medium have played a significant role in its development and continued popularity.
