It is probably the 4th book published by Ruy Duarte de Carvalho, but it seems to be the first where he signs as Rui Duarte, the name he used at the time for his cinematographic work, developed at TPA, and later at the Angola Cinema Institute. This book, published by edições 70 (Lisbon), with a print run of 1000 copies, comprises “7 texts and 10 drawings of mumuíla reference”.
The combination of drawings and text, as well as graphic experimentation, makes it a singular book. The Mumuila Reference results from the production and direction of the “Presente Angolano, Tempo Mumuila“, a documentary series of 10 episodes that he began filming in 1976, in the province of Huila.
