Description: This unusual local post issue features an engraved black-and-white central vignette showing three Manx Shearwaters flying at varied distances over a calm sea channel. A prominent, rugged cliffside representing the local topography rises from the water on the far right side of the horizon line. The grayscale pictorial artwork is beautifully framed by a wide, solid fluorescent orange border carrying the vertical inscriptions "ISLE OF MAN" on the left and "CALF OF MAN" on the right in stark white sans-serif typography. The upper right corner of the central design includes a bold numeric value of "5" positioned directly above the unique regional currency label "MURREYS".
Circa: 1963
Condition: MNH
Notes:
This curious piece belongs to a specialized category known to philatelists as a "Local Post" or cinderella stamp, which was privately produced to cover sea carriage mail delivery from the tiny islet of Calf of Man across to the main postal network at Port St. Mary. The face value is uniquely denominated in "Murreys," a local token currency named after John Murrey, who issued the very first historic Manx coinage back in the seventeenth century. Because these labels were not valid for standard international delivery, they had to be placed strictly on the reverse side of envelopes or alongside official British Royal Mail stamps on the front face.
The Manx Shearwater holds legendary importance as the singular bird species named directly after the Isle of Man. Invasive long-tailed rats completely drove them into local extinction on the islet by the mid-1900s, but following an intensive multi-agency wildlife eradication campaign, the birds famously returned to breed, with over 1,500 pairs safely nesting in underground burrows today.
