This FDC features the 3d Guernsey regional stamp (SG 10) on the front, and the Isle of Jethou 1961 Europa set (3v) on the reverse.
The cover, as shown, is a specific ‘Isle of Jethou – Europa 1961’ version, rather than the generic (not specific to Jethou) version that can also be found.
We have three of this item in stock, all in similar condition to the one pictured.
Part of the Bailiwick of Guernsey, Jethou is a small island, roughly half a mile long, that sits immediately south of Herm. It is owned by the Crown, but leased by a tenant.
Between 1960 and 1969, a period when the island was open to the public, Jethou issued its own local stamps. These were seemingly produced mainly to generate interest and publicity, though postally used examples, affixed to the back of mail from the island, do exist.
Islands within the Bailiwick were no longer allowed to produce their own local stamps once Guernsey gained postal independence in 1969, meaning that Jethou's issues - like those from Herm - ceased.
Further background about Jethou stamps can be found on this website.
