Sleeping Bird is an original pencil and pen drawing realized by Eugène Juillerat (1856 - 1925) in 1920. Good condition on a grey paper mounted on a white cardboard passepartout ( 29x39 cm). No signature. 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
