This blotter art was created by artist Stevee Postman to commemorate the 60th anniversary of Albert Hofmann's discovery of the psychoactive effects of LSD. It is designed in the traditional style found on the street: a 7.5 x 7.5-inch sheet perforated into 900 quarter-inch "hits". It is printed with soy-based inks onto a hemp-blend paper that is chlorine-free, acid-free, and of course, LSD-free.
