Desc: Lisboa, Cidade Triste e Alegre: Directed by João Trabulo. With Leonor Buescu. In the 1950s, Victor Palla and Manuel Costa, two architect friends, portray the city of Lisbon in more than 6000 photographs. These are published in an eponymous book circulated in fascicles, during the fascist regime, but forgotten during the following half century. After their deaths, it becomes the book of photographs with the greatest international projection ever and this film is a tribute to the work of these two figures, which is now 100 years old.
