What is a first day cover:
A first day of issue
cover or first day cover (FDC)
is a postage stamp on a cover, postal card
or stamped envelope franked
on the first day the issue is authorized for use within the country or
territory of the stamp-issuing authority.
Sometimes the issue is made from a temporary or permanent
foreign or overseas office. There will usually be a first day of issue
postmark, frequently a pictorial cancellation, indicating the city and
date where the item was first
issued, and "first day of issue" is often used to refer to this
postmark. Depending on the policy of the nation issuing the stamp,
official
first day postmarks may sometimes be applied to covers weeks or months
after
the date indicated.
