Wooden ruler with prints of scenes from a roll in black and white, which gave rise to the first fiction feature of the film "Aniki Bóbó".

This ruler is part of the Manoel de Oliveira Collection, developed at the inauguration of Manoel de Oliveira's house, promoting the cinematographic universe of the Portuguese director. 

In 2019, the Serralves Foundation inaugurated the Casa do Cinema Manoel de Oliveira, as a new center of reference in the field of cinema and moving images, bringing together the filmmaker's extraordinary documentary nuclei.

Manoel Cândido Pinto de Oliveira was born on December 11, 1908, in Porto. He was the director with the longest career in the history of cinema, in a total of 84 years between his debut as a director (with Douro, Faina Fluvial, in 1931) and his last film (Um Século de Energia, in 2015).

With a filmography that includes more than fifty titles, he was the only filmmaker to move from silent cinema to sound cinema, from black and white to color and from nitrate film to digital support. Having continued to film until the age of 106, Manoel de Oliveira received wide critical recognition, with a work that was awarded at the most important film festivals in the world.
