EXTREMELY FINE. ONE OF TWO KNOWN COVERS WITH THE RARE INDIGO-BLUE SHADE OF THE 2-PENCE "POST PAID" EARLIEST IMPRESSION.
Although experts now accept two different shades and print qualities in classifying the earliest impressions of the 1848 2p "Post Paid" stamp, the Indigo-Blue shade, with its intense depth of impression, is the longstanding and unmatched earliest printing. The Blue shade, with its characteristic "dry" or "sticky" impression, is represented by a group of covers from one correspondence (approximately four or five; see Caspary and David Feldman Mauritius sales). These dry prints are considerably less intense than the Indigo-Blue stamps, a result of the ink failing to adhere to, or flaking off of, the insufficiently moistened grainy paper. While experts have adopted new parameters of print quality in classifying the earliest impressions, there can be no debate over the Indigo-Blue stamps - they are striking examples of the engraver's best and earliest product.
The other recorded cover with the Indigo-Blue earliest impression was in the Dale-Lichtenstein sale (October 21, 1968, lot 7, realized $18,000). It has an uncancelled stamp tied by a manuscript transit marking.
