Vintage 1970s Lucite Art Block, Chinese Jian Zhi Peking Opera Warrior For Sale

This is a clear Lucite (acrylic) art block display piece circa 1976. It was gifted to me, but never "used." It's been tucked away in a memorabilia box for 50 years! It features an embedded Chinese Jian Zhi(paper cut design) imageof a Peking opera warrior dressed in elaborate, military armor with vibrant painted face makeup. Viewing the piece from different angles creates a kaleidoscope prism effect, duplicating and mirroring the image against the sides. It's a great find for lovers of Chinoiserie decor and collectors of Asian art.
Size is 5-7/8" tall, 3-7/16" wide and 1-1/16" thick.
