Butterfly chairs is an original design item realized by Inge e Luciano Rubino in the 1960s. Butterfly (or Model 329) chairs were produced by Soro Stolefabrik. Yellow fabric and wood structure Don't miss an icon of design. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
