Description

Hello!
This auction is for a complete set of color proof singles from the 400th Anniversary landing of the Mayfower in Plymouth Harbor commemorative issued by the USPS on 9/17/2020. These proofs were printed on untagged, self-adhesive stamp paper. The proofs are: offset black, cyan, yellow magenta and intaglio black. A finished and tagged die-cut single is also enclosed.
All of the stamps have been
CLEANLY
cut from their respective sheets. The scan above is a stock scan but the stamps you will receive will be virtually the same in quality.
You may receive top, bottom, left or right margin copies, and if so, ALL stamps will be from the same position on the sheet of 20 (See my other listing for plate number single copies).
2500 sets of these color proofs were issued in full sheets as a limited edition collectors set and sold out in 24 hours.
The USPS describes the production techniques used: "the stamps were first printed using offset lithography, one of the most common stamp production techniques. Known for its clarity and precision, offset printing involves transferring or 'offsetting' the image from an aluminum plate to a rubber blanket that is then applied to the stamp paper. The stamps passed through four offset printing units receiving black ink first, followed by cyan, magenta and yellow....the intaglio step of the process, which occurred last, was by far the most challenging to pull off...the printing requires applying a tremendous amount of pressure."
Regarding the intaglio portion of the stamp design, the USPS says "In England, the Hawthorn---a member of the rose family--is sometimes called a mayflower as it blooms in May. Breeding worked from a photograph of an actual hawthorn blossom to create the stylized intaglio design."
