Portrait is a black and white charcoal drawing realized by Serge Fontinsky (1887-1971) in 1943. Hand-signed and dated on the lower margin. The sheet is glued on passepartout (lightly is worn). Good conditions. 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
