A study on transparency and color shades, a geometric representation of the visual experimentation generated during the Italian sixties, this lamp truly exudes the meticulous research executed by Ugo La Pietra from 1964 to 1969. This particular lamp is the original unique prototype that has been retrieved with permission from the artist Ugo La Pietra from his studio in Milan. Acrylic, painted metal, chromium-plated brass. Provenence: Original prototype directly from the studio of Ugo La Pietra.
