This is from the fourth group of sixteen flag stamps. The series includes the United Kingdom, Barbados, Nepal, Israel, Malawi, Byelorussian S.S.R., Jamaica, and Kenya.
While the designs and colorations of the flags flown at the U.N. are different, the flags are manufactured from identical materials, and cut to identical proportions.
What's a Proofcard?
Limited-Edition Fleetwood Proof Cards bring all the best elements of stamp collecting together. They’re historic keepsakes showing when and where a stamp is issued – philatelic souvenirs that can never be duplicated.
The eye-catching design on the top of the card is known as a cachet. It features historical prints and photos as well as artwork created by world-renowned artists, making collecting them more fun.
The reverse side of the card is filled with interesting background information you’ll enjoy discovering.
Another neat feature is the cancellations. Traditional cancellations are used to mark postage stamps to prevent their reuse. Official First Day cancellations have two parts – a date stamp indicating the date and site where the stamp was released and cancellation bars with the “First Day of Issue” slogan between them. Often the date and location of the cancellation are connected to the stamp topic, adding extra meaning to your proof card.
