In 1975, Kundera moved to France. There he published The Book of Laughter and Forgetting (1979) which told of Czech citizens opposing the communist regime in various ways. An unusual mixture of novel, short story collection and author's musings, the book set the tone for his works in exile. Published in Czech (Kniha smíchu a zapomnění) in April 1981 by 68 Publishers Toronto. This book is also a proof that the owner had an active interest in unofficial literature. We do not know when and under what circumstances copy of this book became part of Mr. Šufliarsky´s collection.
