Priority Mail was established as a sub-class of First Class in 1968. It provided for handling of parcels more than two pounds with an accelerated service. This auxillary marking handstamp was used to designate a parcel that was mailed at this rate.
A handwritten, paper label reading "PM" is taped to top of handle. Black ink stains appear over the base.
