This is the fifth of a series of six 1978 photos of Oscar Niemeyer having lunch in a restaurant, meeting fellow architects. The album from which this photo came was discarded by the owner's family, after she died, and sold to us at a flea market in Rio de Janeiro. We decided to bring this unpublished photo to the Brazilian and international public and mint it on the ethereum blockchain, in order to satisfy the public interest in building the history of one of the most important artistic figures of Brazil.
