A limited edition of signed and numbered selected prints from Dean Chamberlain's Psychedelic Pioneers Series are available from MAPS. The smaller series of Dean's print of Dr. Albert Hofmann is sold out, and the larger series is now available for sale. Three more Pioneer series, the Laura Huxley print, the Ann & Sasha Shulgin print, and the Ram Dass print are now available. Proceeds from the sales support psychedelic research.
