Pair of vintage shelves 1960 string black gold

Old pair of wall shelves (not to be put so) golden metal string and black lacquered sheet metal boards circa 1960 in good condition. They can be combined into one large room. There is a slight difference in patina between each pair of golden uprights. The black boards are clean. These are shelves in the taste of tomado, ideal for a library. Each measures 58 in height by 49 in width and 17cm in depth. The unfolded set measures 143 X 58cm.
