We think that this Prudential Insurance Needle Book was a promotional advertising item from the mid 1960's to the early 1970's. It was made in Japan and is marked as such on one side. The address for this is from Chicago, Illinois 60601.
These needle books appear to be new and unused and are in great vintage condition. There are various types of rust-proof needles in the book along with a needle threader. One needle book has two business stamps on one side for a Mary A. Dabros, a Special Agent for Prudential Insurance in South Bend, Indiana. The other needle book has no markings or business stamp on it.
