Vintage Round VIRGO Astrological Sign Medallion Necklace

Vintage necklace. Says JAPAN on backside. Backside of medallion says; VIRGO Aug. 22- Sept. 22 My guess looking at styling this might be from the 1960’s or 1970’s ? It has wear and chain could be polished. I didn’t polish it because sometimes the base metal is a copper or brass and I didn’t want to make that shine thru. I love the image on from. Looks like a girl with pig tails and a Magic wand. Necklace approx 27” long. Slips over head. No clasp. Pendant approx 1 1/8” diameter
