"Morový sloup", a collection of poetry by Jaroslav Seifert, was published in the samizdat edition Edice Petlici in 1973. The book is supplemented with illustrations by Jan Bauch. Inside is the dedication by the author to Ludvík Vaculík, who was the founder and organizer of Edice Petlici. And in 1986 he made another dedication, "Transforming into the National Archives", referring to the newly-exiled Czechoslovak Documentation Center of Independent Literature, founded by historian Vilém Prečan together with other personalities of Czechoslovak exile. In the seventies, the collection was published several times abroad, and in Bohemia for the first time in 1981.
