One-of-a-Kind LN Chunky Clay, Brass & on sale Laminated Stone Bead and MOP Mother of Pearl Necklace

Unique and original clay, brass and stone bead and mother of pearl choker necklace. Signed LN in on sale script, it was sold to me as Little Nemo but I don't believe it is. It's just not in that L/N style. I've searched online to learn more about this piece and I've only come across one other like it (on Pinterest, photo, no details) in terms of materials combined and in a similar though different style. Certainly a conversation piece! It is in excellent condition and I can only guess as to its age, which I place at around the 1980s. It's chunky and has nice weight. The clasp is in perfect working order. It measures 18" L. You'll be the only one wearing one of these!
