Belgian ball chair by Pierre Guariche for Meurop - Upholstered in a black and white fabric, the seat cushion is dark blue. The seat shell rests on a swivel aluminum tulip base. Very good vintage condition 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
