Originally a refugee from the Russian revolution, his strong opposition to Hitler earned him seven years in various camps, during which time he devised his unique system. Much of the work was done without pencil or paper ? and so most of the steps are performed mentally.* This is a VG copy of the 1st./1st. with minimal age and shelf wear.*
