Vintage Koi Fish Brooch Pendent Combo Gold Tone Pisces VTG 2" Two Entwined Koi Fish Pisces Brooch Pendant This piece is signed on the back, I am unable to make out what it says maybe "MPMIG 80" or "MEING 80" or something similar. I have found several on goggle that are attributed to (MMA - Metropolitan Museum of Art) It measures approximately 2" long by 1" tall. The pin mechanism works and there are two bails to help stabilize it on the chain. Good condition.
