Set of 5 industrial ‘214 gispen’ armchairs with black bakelite armrests. A special dutch design by christoffel hoffman for b.p.m. Which was founded in 1907 and was the precursor of royal dutch shell. The nice thing about this design is that the sled tubular frame ends in a handle above the backrest, giving them an industrial appearance. The chairs have a mark of b.p.m. On the bottom of the seat. 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
