WILSON, Robert Anton. Opium Den.

(No place): Thomas Lyttle, no date.  (c.1995).  Acid blotter sheet designed in the traditional style found on the street: a 9.5 x 9.5-inch sheet perforated into 900 quarter-inch “hits”.  One of the first vanity acid blotter sheets.  A near fine example.  One of 250 numbered copies signed by the late author and psychedelicist Robert Anton Wilson, author of the Cosmic Trigger and Illuminatus series.
