Mid century vintage Brutalist metal art tulip pendant light fixture

Brutalist vintage tulip light fixture pendant. The visible annealing of the metal (copper?) from heat forging produced a wonderful pattern on each of its five "petals". The ends of each petal curve up at the top. This old fixture will need a modern light kit, or weave a long plug-in cord through the top to create a hanging lamp. It measures 8.5 inches tall, 5" diameter at the top and 8" diameter at the bottom.
