Artistic Composition is an original pencil sketch realized by Ronaldo De juan (1930-1989). Artist’s initials and date at the bottom of the left corner. Hand-signed by the artist on the back of the yellowed card. 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
