THE FIRST QUESTION TO BE asked when stamps come into consideration is the very fundamental, "What is a Stamp?" That's
a very simple question, but the answer is complex.
A postage stamp is a tiny piece of paper, representing an obligation by a government to perform a certain postal duty.
It bears an imprinted design and, except with Great Britain, bears the name of the country of origin. Great Britain, as has
been noted before, has never felt it necessary to include the name of the country, but prints the words "Postage" and "Revenue"
on the stamp to denote the use, and generally has the likeness of the King in the design. That is a simple description but
it does not explain any of the very important "technical" aspects of the matter. A postage stamp is produced by any of a number
of printing processes, the two most common methods being engraving and gravure. Most governments prefer engraved designs,
because they look more impressive, and resemble banknotes, but the costs are generally higher, and there are certain limitations
to engravings not met with in gravure or other processes.
Skipping the problems of production for the moment, we see that a postage stamp should first bear the name of the country
of origin, and a value, and then should have an appropriate design and a distinction as to the intended manner of usage.There
is, first of all, the straight postage stamp, which is sufficient to carry a letter, parcel or printed matter from a point
of origin to the ultimate destination. There must be certain values, to meet the postal rates for first, second, third and
fourth class mails, and these stamps should be in accordance with the colors as established by the Universal Postal Union,
in Berne, Switzerland. (The U.P.U., set up in 1875, is an international organization which regulates the handling of mail.)
The so-called straight postage stamp, in addition to its use for regular mail, will carry a letter as well via airmail,
or by special delivery, or parcel post, even though special stamps may have been produced for these purposes. In this country,
for example, stamps are produced for straight postage, airmail and special delivery, and there are or have been stamps for
postage due, registry and parcel post. There are also revenues in one form or another, but the collecting, or skipping, of
these items is a matter for each collector to decide.
Regular postage stamps whose only intended purpose is to carry the mails through, are supplemented by commemoratives or
special stamps, each having a generally limited period of sale.
Measurements of postage stamps are usually 1 inch by 3/4 inches, or 1 1/2 inch by 3/4 inches, with the exceptions either
much smaller or much larger. For the most part present day stamps are perforated on all sides, to facilitate separation, but
this has not always been so and, in fact, is sometimes not true even today.
