Vintage op art/postmodern wall mirror composed of three graduated square mirrors with glass border and metal frame (ca. early 1970s, USA). Stacked mirrored panels give the piece a 'floating effect.' Very good, vintage condition with light scuffs to the metal edging and small spots of discoloration/foxing to the glass, as shown. H: 31.75” x L: 31.75" x D: 0.75”
