The piece dates back to the period form 1960 to 1980. All four sides of the item are covered with glass brutalist surfaces framed by wood frames. This rough mosaic like brutal surfaced glasses were very famous around the mid-century starting from th early 1950's. The piece has a single internal bulb. The glass faces of the piece are similarly decorated with larger glass stones alligned in an enlarging vertical line. The piece would contribute the mystic environment of an interior dearly.
