Ken Terry Donation
The stamp features a portrait of a 20-year-old Queen Victoria. The stamp does not feature the country name because they were the only country at the time using this means of postage prepayment.
Appears to have been purchased from Scott Catalog or Mystic Stamp Co., Inc. in Camden, NY by collector Ken Terry and donated to the UPIKE archives. The stamp was sent sandwiched within a folded instruction card from the Mystic Stamp Co, and the donor himself mentioned the Scott Catalog during email correspondence with the archivist.
One of the first standard adhesive stamps used in Great Britain.
