The Polyphony retail store houses limited editions of vinyl records and Marvel comics. Its clean lines and high-quality materials catch the eye. The narrow floor plan offers space for two custom-made display walls. One presents comic books, each of which is placed in a swivelmounted acrylic display case. The other sepia-tinted wall displays 50 records, each of which is held in place by four stainless steel clips. The sepia colour is repeated in the listening booths, thus creating a vintage feel and giving the otherwise predominantly white room a sense of warmth.
