The London Eye features on a set of commemorative postage stamps issued by Isle of Man Post Office to mark the Thames Diamond Jubilee Pageant.
The first day cover features the royal rowbarge Gloriana and two Manx vessels. A percentage of each sale will benefit the Thames Diamond Jubilee Foundation.
Another stamp features Vital Spark which is one of four replica Viking longboats built to be used in the annual World Viking longboat races held in the Isle of Man.
Both vessels will take part in Sunday's river pageant.
"We are absolutely thrilled Her Majesty The Queen has approved this very special first day cover to celebrate such a historic event, which is expected to be the largest live public event ever held in London," says Dot Tilbury, general manager of Isle of Man Stamps & Coins.
"It is particularly special to us as two vessels representing the Isle of Man will be showcased in the pageant.
"A numbered limited edition of just 1,000, one for every boat in the Pageant, will be carried aboard a vessel in the flotilla and authenticated by the master of the vessel.
"Priced at just £10, I would encourage any royal fan to pre-order their cover now to avoid disappointment."
