An important collection of John Lennon autograph drawings and manuscripts produced by the artist for his critically acclaimed books: In His Own Write (1964) and A Spaniard in the Works (1965). Including 89 lots ranging from $500 to $70,000, this is the largest private collection of John Lennon’s work ever to come to market.
