This is a matching set of 3 armchairs and a coffee table designed by Umberto Mascagni from Bologna/Italy. They are upholstered in the original off-white marbled vinyl with brass and chrome details. Mascagni's furniture was exclusively sold by Harrod's in London, UK, in the late 1950s. The measurements of the table are 50cm high with a diameter of 60cm, and the table top is made of glass. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
