deco moderne ladies pin w/ retractable cord mechanical pencil, ivory celluloid w/ chrome

Retractable mechanical pencil, ivory celluloid on a chrome pinback, early to mid century working girl style! I love this so much, and it really works well. Pulls out and retracts smoothly, no rusting or damage.

It's almost impossible to make out the markings here because of the tarnishing to the back of the pin - it's something, New Jersey. Park Sherman? It looks like a P at the top left corner? The pencil itself is not marked at all.
