National Central Bank had a central office in Lancaster PA. The plastic snap bag was to hold your loan documents or you could put your deposits in it. They developed their own atm access before anyone in that area and the access card was called a Key Card. Their logo was a key. The other item in this lot is a squeeze advertising coin holderembossed with a Key. From a smoke free and pet free home. National Central Bank became Hamilton Bank that eventually became Wells Fargo through a few mergers.
