This is a wonderful old Authentic Mings of Honolulu Bamboo Leaf Pin. It is 55mmx35mm at the largest dimensions. It is signed "MINGS" in red/brown ink on the back. It was found at a local estate sale. I do not know much about it, please use pictures for reference. I would be happy to upload more if needed. Pin is slightly bent. Any questions ask! Shipping is USPS 1st Class with Tracking.
