This pair of armchairs, Prestigio Line, was designed by Daciano da Costa for Metalúrgica da Longra, in Portugal, in 1962. "In contrast with the existing habits of the country, this series of furniture for public spaces proposed a modern understanding of space – fluid and visually unobstructed – by using essential, light and airy structures, in combination with a certain biomorphism, of undeniable elegance, which was in line with international production at the time." - from Daciano da Costa's website. It is a metal structure, painted in black, with black faux-leather upholstery. This pair is in original and good vintage condition, with some small rips on the fabric. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
