The present model 'Ultrafragola' mirror was designed by Ettore Sottsass Jr. as part of a series, 'I Mobili Grigi', first exhibited in 1970 at the Eurodomus, Milan. The present lot was made from a carved wood frame and belongs to the first series of mirrors realised by Poltronova before 1971. Examples of the 'Ultrafragola' mirror executed after this date instead feature a metal structure, which was introduced to create a more sinuously curved form.
