The History of the Psychedelic Movement is a cartoon and coloring book published in 1967 by Timothy Leary, Art Kleps, and friends at their infamous Milbrook, New York estate. A rare copy is currently up for auction on eBay with a BuyItNow price of $750. From the item description:
I purchased this from an officer that worked in the Poughkeepsie Township police department. He obtained it from the Dutchess county S.O. before they burned several hundred copies that had been confiscated from the Millbrook Estate raid.Timothy Leary coloring book (eBay)
Very few copies of this book are in existance. Art Kleps himself didn't have a clean copy. I will also include and email of a correspondence between the cop and Art Kleps in 1996. Kleps also stated that the remainder of the inventory was lost in Vermont.
