Composition is an original etching, realized by the artist Mario Gianmarco. Hand-signed on the lower right. Numbered, Edition 67/70. The artwork represented skilfully with geometric shapes in a well-balanced composition. In very 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
