This pair of armchairs was produced by the Polish company Swarzędzka Furniture Factory. The armchairs have been reupholstered in a green material and the beech elements have been cleaned and polished with a lacquer. 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
