Paperweight, clipboard and pencil holder set. DAVID MARSHALL. Seville, 20th century. Aluminum and brass. Designer's stamp on the base. Measurements: 7 x 12 x 12 cm; 12 x 9 x 7.5 cm; 3 x 5 x 7.5 cm. Set of office supplies (paperweight, paper holder and pencil holder) designed by David Marshall, with the star materials of the Sevillian company: aluminum and brass fused by gravity to the sand, using artisanal methods whose origin dates back to Roman culture. David Marshall's pieces, opened in the 1980s, "have stood the test of time and have become design classics," according to the creators themselves. For them, the pieces "must satisfy a basic sensual and sculptural concept (the need to feel, touch, caress...) and another fundamental premise: efficiency and functionality".
