Paul Avery built a secret darkroom in the rafter portion of his apartment building in Warsaw in order to further investigate an incident he was involved in that transpired in mid-1961. When Avery's darkroom was discovered in 1987 among the items found were 3 additional notebooks, handmade darkroom equipment, a huge enlargement of the reconnaissance image, a Soviet record player, a short super 8mm film, a wood architectural model of Avery's apartment building, a tall square wooden box with a handle, and 417 LP records, mostly American, African, Caribbean, and Latin Jazz, as well as dozens of American, and British film Sountracks.The most startling item uncovered was a personal note from Polish jazz legend Krzystof Komeda (1931-1969), he is known for working with Roman Polanski on several soundtracks including Knife int he water and Rosemary's Baby. Komeda begins the note with "My dear Pawel, clearly written to a close friend. Avery lived just down the streed from Stodola, the first official jazz club in Poland where it is speculated that he befriended Komeda in 1953.The shape of the cutaway view is unique to the replica, and indicates the area known during WWII as the Warsaw Ghetto, where Avery was born. The X marks the location of his apartment building just outside the former ghetto, when he returned to Warsaw as a British Secret Service Agent.
