Study For An Arm is an Original Carbon Pencil Drawing realized by Pierre Georges Jeanniot in the early 20th century. The Drawing is in good condition on a yellowed cardboard. No signature. Others sketches on the back of the cardboard. 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
