What
is an Event Cover:
In
philately, a
cachet
is a printed or
stamped design or inscription, other than a cancellation or pre-printed
postage, on an envelope (my items are printed on a #6 envelope
6.5″x3.75″) to commemorate a postal or philatelic event. There are
official and private (independent of postal authorities) cachets. They
commemorate everything from the first flight on a particular route, to the
Sports Events. Cachets are also frequently made, either by individuals or a
government, for first Day of Issue, first day stamp events or
“second-day” stamp events. They are often present these event covers.
