DescriptionLicense plate: 1950 New Jersey motor vehicle registration plate for passenger vehicle. Pair as issued. Stamped metal, 6-1/2" high x 10-3/4" high; paint: black letters on straw (or buff) background: HO 18S Found at 703 Clinton Street, Hoboken. Hudson County was designated on the plates then by a two letter code, HA to HZ or IA to IZ. Thus HO = H for Hudson County and the O is one of the assigned second letters in that code system. It cannot be definitively stated that HO designated it for use on a HOboken vehicle.
