Suppermannerism
American style of interior decoration dating from the 1960s employing odd optical tricks, synthetic materials that were either shiny and mirror-like, or transparent, and over-sized elements, so it was referred to as ‘mega-decoration’, and owed more to images in Superman comics than to Mannerism. 2. Term applied (1970s) to large Post-Modernist buildings. (Curl & Wilson, 2016)
